Jordan has never conducted a nutrition survey to determine nutrient and energy intakes. The current study aimed to describe the energy and macronutrient consumed by the Jordanian population. A cross-sectional food consumption study was conducted, including a sample of Jordanians using two non-consecutive 24-h dietary recalls (24-h DR) between October 2021 and March 2022. A total of 2145 males and females aged 8 to 85 years old living in households were studied. The average of two 24-h DRs for each individual was converted into energy and nutrient intakes. After measuring weight, height, and waist circumference, the body mass index (BMI) and waist-to-height ratio (WHtR) were calculated. The percentage of under-reporters was higher in women than men (58.2% vs. 45.9%). Adults and older adult women had the highest prevalence of obesity (29.6%), while adults and older adult men had the highest prevalence of overweight (41.4%). There is a significant increase in energy intake in children, boys, and all adults, compared to the recommended calories. The mean energy percentage (E %) of total fat was 38%, exceeding the upper limit of the Acceptable Macronutrient Distribution Range (AMDR). At the same time, the mean daily dietary fiber intake fell below the recommended levels (ranging from 13.5 g in children to 19.5 g in older adults). The study population consumes more fat and less fiber than the recommended levels. Actions must be taken across all age groups to correct the deviation of energy and macronutrient intakes from the recommended dietary allowances.
Food consumption and dietary habits are being studied extensively around the world; to better understand the role of nutrition in disease prevention and to identify the root causes of public health issues such as obesity, which is a major risk factor for a variety of non-communicable diseases (NCDs) including cardiovascular, kidney disease, type 2 diabetes mellitus, and some cancers1. In recent decades, dietary patterns worldwide have changed rapidly and dramatically. The changes are characterized by increased processed food consumption, leading to increased saturated fat and simple sugar consumption2. These changes have been linked to overweight and obesity and an increased risk of developing NCDs3. In 2016, the global prevalence of overweight and obesity was around 39% and 13%, respectively, of the adult population4. Jordan also had a higher prevalence of adult overweight and obesity, with approximately 75% of men and women being overweight or obese5.
Food consumption is estimated indirectly through methods such as household food purchases or food balance sheets. Because they provide more food information consumed, data from household and individual food consumption surveys are frequently used to estimate food consumption6.
Individual food consumption surveys are quite often preferred because data is gathered at the individual level, allowing for comparisons across age and gender groups; thus, they provide the data required to measure nutrient intakes and their adequacy7.
Despite this, Jordan had not previously collected data on individual energy and macronutrient intakes. Surveys describing diet and nutritional status are required to monitor the nutritional status of the population, reveal trends in their health and dietary practices, establish links between food and health, identify age groups at nutritional risk, and develop and implement nutritional policies that are tailored to reflect changes in dietary consumption8,9,10.
Despite the importance of such surveys, some countries conduct them continuously over time, others regularly (annually or biennially), and others irregularly6. Furthermore, most countries have undertaken one or more individual-level dietary intake surveys. Some surveys targeted people from infancy to the elderly11, while others were only adults1.
Most surveys used 24-h dietary recalls (24-h DR) as the primary method for assessing dietary intake, with recall frequencies ranging from one to three, either face-to-face or by phone3,12. In addition, a food frequency questionnaire, estimated dietary records, and diet histories were used1,13,14.
In Jordan, assessment of dietary intake using the primary method (24-h DR) was used on a small population for assessing specific nutrients. To the best of our knowledge, this will be the first comprehensive study of Jordanians' dietary intakes and anthropometric measurements, serving as a baseline for future regular surveys. As a result, the current study aims to evaluate and present descriptive statistics on energy and macronutrient intakes and identify subgroups at risk of deficient or excessive macronutrient intakes.
Materials and methods
A cross-sectional study of Jordan's Population-based Food Consumption Survey (JPFCS) was carried out between October 2021 and March 2022. In this study, a part of the JPFCS's collected data is analyzed and presented.
The sample size was calculated based on the estimated population of the Kingdom by Governorate, Locality, Sex, and Household in 202015. The minimum sample size needed within a margin of error of 5%, and a confidence level of 99% was estimated as 664 households; however, to have higher power, the sample size was expanded to 701 households with a total of 2721 household members were contacted, of which 632 households agreed to participate with 2145 (70.8%) household members.
All the people aged eight years and older residing in the selected private households consented to participate. The participants were divided into four age groups (8–12, 13–19, 20–64, and 65 years and older).
Children under eight in the chosen households and pregnant or lactating female subjects were excluded from the study.
Individuals who agreed to participate in the survey received detailed information about the objectives; parents were asked for oral approval for their children to participate. No incentive money was offered for taking part in the survey. The Institutional Board Review (IRB) committee at The Hashemite University reviewed and approved the survey protocol (No.7/13/2020/2021). After receiving oral permission from the head of the household, one of the participant's parents signed an informed consent form for children and adolescents, and data collection began in the presence of parents during the first visit. Informed consent was obtained from the other participants of the household. Informed consent was obtained from all subjects and/or their legal guardian(s).
Data were collected by a trained interviewer who has a nutrition background. Each chosen household was only visited once. During the visit, the participants completed a face-to-face questionnaire on sociodemographic data, general health data, and intake of dietary supplements. Weight, height, and waist circumference were measured. Two non-consecutive 24-h DR was also conducted, the first of which was a face-to-face interview, while the second 24-h DR was collected via telephone.
Two non-consecutive 24-h DR obtained dietary intake for all age groups (weekday and weekend). The days of reporting were randomly selected, but participants were able to change them according to their availability for the interview. For children, the 24-h DR was administered in the presence of one of the parents. Participants were asked to recall and state all foods and beverages, including their quantity, preparation method, and most commonly consumed food brand names, from midnight to midnight the previous day. Various portion estimating aids, such as household measurement items and food models, were used; additionally, a well-known idea about the quantity was created by using a colored food atlas containing over one hundred foods and composite recipes consisting of photos of various foods and meals commonly consumed in Jordanian diets—a series of at least four photographs depicting portion sizes for each food item. To calculate the average dietary intake of energy and macronutrients. The consumed food items are linked to the following databases: ESHA's Food Processor®, Nutrition Analysis Software (version 11:0; ESHA Research), Composition of Local Jordanian Food Dishes16, and Lebanon Food Composition Data: Traditional Dishes, Arabic Sweets, and Market Foods17 were used to analyze the food intake of the two recalls. The average total energy and macronutrient intake for all age groups was calculated.
Anthropometric measurements, including height, weight, and waist circumference, were performed in all age groups according to standards by a trained nutritionist. Height was measured to the nearest centimeter, with participants in a standing position with light clothing and barefoot, using a portable wall stadiometer. Body weight was measured to the nearest tenth of a kilogram in the same conditions using a digital scale (Microlife WS 50. Widnau. Switzerland). Waist circumference was measured using an anthropometric tape at the level of the narrowest point between the lower costal border and the iliac crest18. Body mass index (BMI)(kg/m2) was calculated from the height and weight measurements according to Quetelet's formula18: BMI = weight (kg)/height (m2) for adults. The Body Mass Index-for-Age Z-Score (BAZ) was calculated for children and adolescents. For the association of BMI-for-age with overweight and obesity, values > + 1 SD represent overweight, and values > + 2 SD represent obesity according to WHO reference curves (2007). Values between + 1 SD and − 2 SD were considered normal, and values > − 2 SD were considered thin or underweight19. For adults and older adults, BMI classified as < 18.5 kg/m2 represents underweight; 18.5–24.9 kg/m2 represents normal weight; 25–29.9 kg/m2 represents overweight; and when BMI ≥ 30 kg/m2, the participant classified as obese20.
The waist-to-height ratio (WHtR) was calculated by dividing the 'participant's waist circumference by their height18. A WHtR cutoff of ≥ 0.5 is generally accepted as a universal cutoff for obesity in children (aged ≥ 6 years) and adults21. However, some subjects in the children, adolescent, and adult groups refused to have their weight and waist circumference measured.
Misreporting of energy intake
Energy intake (EI) misreporting in self-reported dietary methods, particularly underreporting, is a well-documented phenomenon observed in children and adults. It was observed in all individual self-reported dietary methods using 24 h DR. The basal metabolic rate (BMR) was estimated using the Schofield equations22 based on weight, age, and sex. The reported daily EI ratio divided by the estimated BMR was calculated as a measure of the underreporting degree. Participants with EI: BMR ratio of < 1.2 were classified as under-reporters (UnR); EI: BMR of 1.2–2.4 as plausible (PR); and EI: BMR of > 2.4 as over-reporters (OvR) for EI as suggested by Goldberg et al.23 and Black24.
Based on the two collected 24-h DR, the average energy and macronutrient intakes of the plausible energy intake reporter participants were calculated and presented. The average daily carbohydrate, protein, and fat intakes were calculated as a percentage of total daily EI and compared to the Acceptable Macronutrient Distribution Ranges (AMDR), which serve as a guideline for the accepted percentage of macronutrient intake25. To calculate energy expenditure, BMR was multiplied by the assumed physical activity level (PAL), which was set at 1.55 for all respondents.
Analysis was conducted using SPSS software (IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp). All analyses were stratified by gender and age group. Sociodemographic and anthropometric characteristics were described using frequencies and percentages for categorical variables. The energy and macronutrient intake distribution was reported as means and standard deviation (SD). A paired samples t-test was used to compare energy intake and expenditure differences. A chi-square (χ2) test was performed to examine the differences between categorical variables. The independent sample t-test was used to test the difference in macronutrient intakes among both genders. The normality of the distributions was assessed through the Kolmogorov–Smirnov test and Kurtosis and Skewness values. Differences were considered significant at p < 0.05.
Ethical approval and consent to participate
The study was conducted according to the guidelines of the Declaration of Helsinki. The Institutional Board Review (IRB) committee at The Hashemite University reviewed and approved the survey protocol (No.7/13/2020/2021).
General characteristics of JPFCS
A total of 2145 individuals participated in this study, of whom 954 (44.1%) were males, and 1200 (55.9%) were females; their general characteristics are presented in Table 1. Most of the study population were adults; aged 20–64 years (66.6%) and geographically distributed in the central governates in Jordan (62.1%). Nutritional supplements were consumed by approximately 21% of the subjects studied, with Vitamin D supplements having the highest contribution, and the mean family size was 4.5 people in the studied sample. Moreover, nearly half of the sample (49.8%) reported having a household income of less than 500 Jordanian dinars (JOD).
In the baseline data of our study, both genders were found to be almost similarly distributed in all other characteristics except dietary supplement use, which was shown to be used by females more frequently than males (28.6% vs. 11.1%) (Table 1).
The anthropometric assessment of the JPFCS study population is shown in Table 2. A significant (p = < 0.001) difference in overweight and obesity status relative to gender. Males were more likely to be overweight than females (42.1% vs. 28.9%, respectively) among adults ,and females were more likely to be obese for the age mentioned earlier than males (29.7% vs. 20.7%, respectively). Moreover, there was a significant (p = 0.012) difference in overweight and obesity status among older adults based on gender. Males were more likely to be overweight than females (44.0% vs. 28.6%, respectively), and females were more likely to be obese than males for the same age (53.1% vs. 24.0%, respectively)..On the other hand, males across all of the JPFCS age groups had larger percentages of abnormal ratios in terms of WHtR compared to females in the same age group. Furthermore, the adults category had the greatest abnormal WHtR (66.3% for males and 58.4% for females), which was statistically significant (p = 0.002), while the ratio was abnormal in less than 30% of males and around 23% of females in both other age categories.
Descriptive analysis of the EI misreporting among the JPFCS study population
As shown in Table 3, 52.8% of JPFCS participants underreported their EI, while only 2.2% overreported; female participants tend to have a higher proportion of EI reporting (58.2%) than males (45.9%), which was significantly different (p = < 0.001). As the JPFCS study population was stratified according to gender and age, both genders tend to under-report their EI and become less reliable when reporting it.
Although males during adolescence and early adulthood years have the same proportion of being UnR (47.8%), adult females tend to have a higher proportion of being UnR (61%) when compared to UnR adolescent female girls (54.4%). Additionally, older adult males and females have the highest EI reporting percentage (60% and 70.8%, respectively) compared to other age categories. Interestingly, none of the females aged 65 years and older in the JPFCS study population OvR had their EI, and only one male (2%) reported it (Table 3).
Energy and macronutrient intakes among the JPFCS study population
Among the study population, 47.2% were among the plausible EI group. Those 'participants' dietary intakes were included in the analysis to produce our JPFCS nutritional assessment. Table 4 presents the mean daily energy and macronutrient intake consumed by the selected study population. Male adults consumed a higher average amount of energy (2907.5 kcal), followed by adolescent boys (2758.6 kcal) and 'males' older adults (2513.5 kcal). While adolescent girls' mean daily EI is the highest (2220.9 kcal), followed by adult females (2209.3 kcal), female in older adults age has an average EI of (2039.1 kcal). With a p-value of 0.05, both genders have a significantly higher average of EI (2757.7 kcal vs. 2614.5 kcal for males and 2161.7 kcal vs. 2096.6 kcal for females) than EE, as shown in Fig. 1, which also displays differences in total daily EE and EI across all age groups. In contrast, the average daily EI of children boys and adult males is significantly higher than their average EE (Fig. 1a and c; p-value < 0.05), only the average daily EI of adult females is significantly higher than their average EE (p-value = 0.045) (Fig. 1c).
On the other hand, female older adults consumed a higher protein intake (15.9%), followed by male adults (15.8%) and male older adults (15.0%). All age/gender groups' intakes of protein and carbohydrates were within the typical ranges for a balanced diet (45–51% and 13–16%, respectively), while all participants (rather than age group or gender) had a higher tendency to consume a higher percentage of fat exceeded the daily recommendation (36–42%). Regardless of gender, it was apparent that low fiber intake was consumed by children, adolescents, adults, and older adults (14.5 g, 17.5 g, 16.3 g, 19.0 g, and 20.0 g, respectively). Furthermore, the average beverage consumption was the highest among older adult males (3080 ml) and the lowest among children girls (1570 ml) (Table 4).
Individual nutrition surveys for examining food consumption patterns and their relationship to population-level energy, macronutrient, and micronutrient intakes have gained recognition worldwide; however, studies investigating food consumption based on individual nutrition surveys are lacking in the Eastern Mediterranean Region. The current study describes Jordanian children, adolescents, adults, and older adults' energy and macronutrient intakes. To the best of our knowledge, this is the first population-based study that estimates energy, macronutrient, fiber, and beverage intakes among Jordanians and in this region.
The general population's use of dietary supplements has been extensively studied. In the current study, 20.9% of participants (11.1% of males and 28.6% of females) used at least one dietary supplement, and the most commonly used supplements were Vitamin D, multivitamins, and omega 3, respectively. One possible explanation for why vitamin D is the most frequently used supplement is that in Jordan, the prevalence of vitamin D deficiency among males was 54% and 78.5% among females26. In another study, multivitamins were reported to be the most commonly used dietary supplements among Jordanian adults, followed by vitamin D and C27.
Energy intake is one of two components of energy balance; positive energy balance occurs when EI exceeds EE, which usually results in weight gain, defined as being overweight or obese. Using BMI as an anthropometric index for determining obesity, the current study found that approximately 60% of adults and older adults were overweight or obese, while 37% of children and adolescents were overweight or obese.
Many Jordanian studies reported the prevalence of overweight and obesity across all age groups except for EI. According to a multipurpose national household survey, approximately three-quarters of men and women aged 18–90 were overweight or obese5. In a nationwide, cross-sectional study of children aged 6–17 years conducted in 2015, the overall prevalence of overweight and obesity was 17.3% and 15.7%, respectively28. The findings of the current study were consistent with previously published studies. Using WHtR as another measure to define obesity, 46% of men and 54% of women were determined to be obese, which was consistent with Ajlouni et al.5, who reported that 60.4% of men and 75.6% of women were obese. Even though a cutoff of ≥ 0.5 is widely accepted as a universal level for obesity in children (aged ≥ 6 years) and adults21, the WHtR has not been studied extensively in Jordanian children and adolescents. Al Hourani and Alkhatib (2022) reported that 12.2% of children aged 10–14 years in a sample of 793 from the Amman subdistrict had abnormal WHtR29.
Energy intake has been extensively studied globally on various age groups using assessment methods with small or national sample sizes. Underreporting is still a problem that should be addressed in surveys designed to estimate EI; in our study, we estimated that 52% of the population was UnR. In the Belgian national food consumption survey on the population aged 15 years and older, 20% of the respondents were UnR30. Lundblad et al., 2019 reported a similar proportion in a population-based sample of Norwegians aged 40 to 99 years1. Also, similar results were reported in the Australian national nutrition and physical activity survey, though 28.6% of the respondents considered UnR using the Goldberg method, it was 44.5% using the predicted total EE method31. In the German national nutrition survey II, the proportion of UnR is 23% for the diet history interviews, 22% for the weighed food records, and 16% for the 24-h DR32. Malaysian adult nutrition surveys in 2003 and 2014 reported that the UnR of EI was 53.6% and 61%, respectively33.
The proportion of UnR varies widely; this can be attributed to various factors such as dietary assessment methods, female gender, increased age, and obesity32. The current study's findings correlate to these factors associated with UnR; furthermore, the first study used a 24-h DR to assess EI in a large population of different age groups, with a large proportion of females.
The current study found a significant increase in EI versus EE in both genders across the entire population, with a significant increase in EI observed in particular among male children and adult males and females. Regardless of these findings, an average of two 24-h DR of EI is not a good predictor of daily EI, particularly in light of the increased prevalence of obesity across all age groups. In addition to the fact that the lockdown during the COVID-19 pandemic also contributed significantly to global obesity rates34
Given Jordan's lack of food consumption data, researchers from other countries have reported comparable food consumption and nutrient intake findings. In the current study, for the total population; carbohydrate and protein contributions to EI (48.1% and 15.2%; respectively) were within the AMDR (45–65% of carbohydrate for all age groups and 10–30% of protein for children and adolescent, and 10–35% for adults and older adults). Nonetheless, carbohydrate contribution to EI was lower in older adults than in AMDR (44.5%). The most conspicuous finding was that fat consumption was higher across all age groups than in the AMDR ranges (25–35% for children and adolescents and 20–35% for adults and older adults), exceeding 35% and even 40% in older adults. The contribution of carbohydrates, protein, and fat to EI has been studied at the population level in many countries, particularly developed ones, but to a lesser extent in Middle Eastern countries. The carbohydrate AMDR is characterized by a wide range of 45–65%, and the contributions of total carbohydrates to EI was between 45 and 49% were reported for studies performed in Belgium (45.8%), Norway (42%), Lebanon (48.9%), Italy (45%), and Canada (49.3%)1,11,12,30,35. Other studies reported carbohydrate contributions of 50–59% in Malaysia (53%), Brazil (56%), the UK (50%), and the US (50.5%)2,33,36,37; and remarkably, (71%) in the Philippines and (66.7% in women) in Mexico38,39. The current study's findings are consistent with the Lebanese community12; the amount of carbohydrates consumed depends on the type of food habits; in Jordan, three carbohydrate sources contribute to total carbohydrate intake: bread, which is a basal food; rice, which is a primary component of lunch meals; and sugar and desserts.
The 'adult's AMDR of fat ranges between 20 and 35%, with the utmost recommended for less than 30%. The mean contribution of fats to total EI was 38% in all age classes except in older adults (41%). According to surveys conducted in different countries with national samples of adults, the mean proportion of energy from fat in Lebanon (36.9%)12, Belgium (37.9%)30, Norway (35%)1, Italy (36–37%)11, UK (35%)36, US (32%)37, Hungary (36.1–38.9%)40, Canada (33.8)35, and Malaysia (31%)33. Nonetheless, studies in Brazil and the Philippines found that fats contributed 27% and 17% of total EI, respectively2,38.
Since the current study included children and adolescents, the contribution of fats to total EI for both age groups was nearly 37%. Some national or population-based studies emphasized fat's average contribution to total energy. In Brazil, the mean contribution of total fat to EI was 27% in the age groups 10–13 and 14–18 years2, 36.2% in Belgium30, 37% in Italy11, and 34.8% in the UK36.
The current study reported that the contribution of fat to EI was 41% in older adults (≥ 65 years). According to studies that included the elderly as a subset of the entire population, the Brazilian elderly had the lowest contribution of total fat to total EI (26% for men and 27% for women)2, whereas 39–39.9% in older age categories (60–74 and > 75 years) in Belgium30, 34% in Italy11, and 33.4% in Canada35.
The increased contribution of fat to EI in the current study could be attributed to a variety of factors, including changes in food habits during the COVID-19 pandemic lockdown, which were characterized by increased home preparation of foods, particularly traditional sweets, and desserts; reliance on Westernized diets, particularly among children and adolescents; and cooking methods, which could include frying and deep frying. As a result, future work into the fat contents of polyunsaturated, monounsaturated, saturated fat, cholesterol, and trans fat should be conducted.
Protein contributed 15.2% of total EI, within the AMDR for all age groups. Among the reported macronutrient intake data, many studies found the protein within AMDR, whereas carbohydrates and fat were not. In national and population-based studies conducted in Italy, Norway, Canada, the US, the UK, Mexico, Brazil, Belgium, Malaysia, and the Philippines1,2,11,30,33,35,36,37,38,39, the protein intake was found to be within AMDR.
The results of the current study were in accord with those of previous studies. In addition to total protein consumption, some studies reported protein consumption by sources, such as animal or plant protein. Conferring to a Brazilian study, more than 50% of the total protein consumed was of animal origin2. According to some studies, animal protein consumption among Dutch adults decreased across all age groups in the 2012–2016 national food consumption survey compared to the 2007–2010 survey3. Also, the average daily protein intake in the Hungarian population was near 60/40% animal/vegetable protein ratio40. The current 'study's result on protein consumption might need further analysis to quantify the ratio of animal to plant proteins.
Although the average daily intake increased with age, ranging from 13.5 g in children to 19.5 g in older adults, fiber consumption was considerably lower than the recommended levels for all age groups, which were set at 14 g/1000 kcal41 or more than 25 g /day42.
The results of our study are entirely consistent with studies in other countries, which also reported inadequate dietary fiber intake, Slovenia43, Brazil2, the Philippines38, Norway1, Spain44, Finland45, and Hungary40. Even though fiber intake was inadequate in all age groups, the current study found that fiber intake increased with age; this finding is consistent with a previous Italian study on a population (0.1–97.7 years), which reported that the mean daily intake of dietary fiber increased with age and ranged from 8 g per day in infants to 22 g per day in the elderly11. These findings appear to be possible because children and adolescents consume more fast and refined foods, whereas the elderly prepare more meals at home from raw fruits, vegetables, and grains, which contain more dietary fiber.
In surveys seeking information on EI, beverage consumption must be assessed. A limited number of studies estimated beverage consumption, which included water, coffee/tea, and soft drinks (sweetened or unsweetened). The average total beverage intake in the Spanish study was 850 g/day, with water and sugary soft drinks contributing 569 and 88 g/day, respectively46. According to the Danish study, individuals below the lowest quartile of the diet quality index consumed more sugar-sweetened soft drinks, while those above the highest quartile consumed more water47. According to another study, beverages, particularly sugary beverages, account for 17.1% of total energy consumption in Brazil48. Further analysis of the current study data on beverage consumption is required to categorize it into different types, such as water, tea/coffee, sugary soft drinks, and others.
The current study's findings can, at least partly, explain the role of dietary factors in the increased prevalence of overweight across all age groups and the progression of chronic non-communicable diseases in Jordan. Furthermore, this study was conducted following the COVID-19 pandemic and its effects on food habits and nutrient intake. The study's dietary profile can help support initiatives to lower the prevalence of obesity and diabetes mellitus.
Our findings provided important insights into the dietary patterns of the Jordanian population, revealing some nutrient deficiencies as well as excessive nutrient intake. It is also necessary to reduce fat consumption while increasing fiber consumption. More efforts are needed to improve the diets of older children and adolescents. It will also be necessary to monitor its progression.
Future research is required in a variety of areas, such as dietary habits for age groups that are at risk, like pregnant women and young children, the connection between energy and macronutrient intakes and obesity across all age groups, but particularly in children and adolescents, and the need to conduct regular surveys of food consumption to track changes over time.
Strength and limitations
The current study has several strengths: first, it is noteworthy that this is the first population-based study designed to estimate dietary consumption in Jordan. Second, a large population sample of 2145 people aged 8 to 85 years old was recruited; third, rather than self-reporting, participants' heights, body weights, and waist circumference were measured, resulting in much more accurate assessments of BMI and WHtR.;
The study has some limitations that should be considered: the fact that some of the participants were under reporters is a general limitation of all dietary assessment methods, including the current study. Data on physical activity were not obtained. Because the study was cross-sectional, establishing causality between the variables studied was difficult. Another potential limitation is that no biological samples, such as blood or urine, were collected, and no blood pressure was measured.
