BACKGROUND: Nutritional status of women during pregnancy has been considered an important prognostic indicator of pregnancy outcomes. OBJECTIVES: To investigate the pattern of gestational weight gain (GWG) and gestational diabetes mellitus (GDM) and their risk factors among a cohort of Emirati and Arab women residing in the United Arab Emirates (UAE). A secondary objective was to investigate pre-pregnancy body mass index (BMI) and its socio-demographic correlates among study participants. METHODS: Data of 256 pregnant women participating in the cohort study, the Mother-Infant Study Cohort (MISC) were used in this study. Healthy pregnant mothers with no history of chronic diseases were interviewed during their third trimester in different hospitals in UAE. Data were collected using interviewer-administered multi-component questionnaires addressing maternal sociodemographic and lifestyle characteristics. Maternal weight, weight gain, and GDM were recorded from the hospital medical records. RESULTS: Among the study participants, 71.1% had inadequate GWG: 31.6% insufficient and 39.5% excessive GWG. 19.1% reported having GDM and more than half of the participants (59.4%) had a pre-pregnancy BMI ≥ 25 kg/m2. The findings of the multiple multinomial logistic regression showed that multiparous women had decreased odds of excessive gain as compared to primiparous [odds ratio (OR): 0.17; 95% CI: 0.05-0.54]. Furthermore, women with a pre-pregnancy BMI ≥ 25 kg/m2 had increased odds of excessive gain (OR: 2.23; 95%CI: 1.00-5.10) as compared to those with pre-pregnancy BMI < 25 kg/m2. Similarly, women who had a pre-pregnancy BMI ≥ 25 kg/m2 were at higher risk of having GDM (OR: 2.37; 95%CI: 1.10-5.12). As for the associations of women's characteristics with pre-pregnancy BMI, age and regular breakfast consumption level were significant predictors of higher pre-pregnancy BMI. CONCLUSIONS: This study revealed alarming prevalence rates of inadequate, mainly excessive, GWG and GDM among the MISC participants. Pre-pregnancy BMI was found a risk factor for both of these conditions (GWG and GDM). In addition, age and regular breakfast consumption were significant determinants of pre-pregnancy BMI. Healthcare providers are encouraged to counsel pregnant women to maintain normal body weight before and throughout pregnancy by advocating healthy eating and increased physical activity in order to reduce the risk of excessive weight gain and its associated complications.

Human milk oligosaccharides (HMOs), phospholipids (PLs), and gangliosides (GAs) are components of human breast milk that play important roles in the development of the rapidly growing infant. The differences in these components in human milk from the United Arab Emirates (UAE) were studied in a cross-sectional trial. High-performance liquid chromatography‒mass spectrometry was used to determine HMO, PL, and GA concentrations in transitional (5-15 days) and mature (at 6 months post-partum) breast milk of mothers of the United Arab Emirates (UAE). The results showed that the average HMO (12 species), PL (7 species), and GA (2 species) concentrations quantified in the UAE mothers' transitional milk samples were (in mg/L) 8204 ± 2389, 269 ± 89, and 21.18 ± 11.46, respectively, while in mature milk, the respective concentrations were (in mg/L) 3905 ± 1466, 220 ± 85, and 20.18 ± 9.75. The individual HMO concentrations measured in this study were all significantly higher in transitional milk than in mature milk, except for 3 fucosyllactose, which was higher in mature milk. In this study, secretor and non-secretor phenotype mothers showed no significant difference in the total HMO concentration. For the PL and GA components, changes in the individual PL and GA species distribution was observed between transitional milk and mature milk. However, the changes were within the ranges found in human milk from other regions.

Dietary supplement intake and associated factors among gym users in a university community in Sharjah, United Arab Emirates (UAE), were assessed using a structured, self-administered questionnaire in this cross-sectional study. Adults (N = 320) from five gyms in the University City of Sharjah participated in this cross-sectional study. The prevalence of dietary supplement intake was 43.8%. Statistically significant associations were found between the use of dietary supplements and sex (47.7% males, 28.1% females; p = .006), as well as weight lifting (88.6% taking supplements vs. 11.4% not taking supplements; p < .001), favoring male gym users. The reasons attributed to the use of dietary supplements varied between the sexes. Male exercisers used supplements to increase or maintain muscles mass, strength, and power and to boost exercise recovery. Females mainly used dietary supplements to increase energy, maintain their health, and prevent nutrition deficiency. Overall, protein supplements (whey proteins [48.6%] and protein powder [45.7%]) were among the most-consumed dietary supplements, followed by multivitamins (38.6%), branched-chain amino acids (36.4%), caffeine (35.0%), and creatine (29.3%). A widespread use of Internet-driven, self-prescribed dietary supplement intake was reported among gym users (60.7%). Only 12.8% of dietary supplement users sought information from dietitians. Practical implications suggest that gym instructors and coaches should be sufficiently trained to be able to provide accurate and scientifically sound information on dietary supplements to the exercisers in gyms in the university environment.

BACKGROUND: The practice of menu labeling is gaining popularity worldwide as a potential policy to reduce energy intake as a means to decrease the prevalence of obesity. So the purpose of the present study is to identify the knowledge, attitudes, and practices of adults regarding the implementation of menu labeling in dine-in restaurants. METHODS: A cross sectional survey included 2020 male or female adults (aged ≥ 18 years old) participants was collected from two cities in the United Arab Emirates(UAE). The participants filled a validated questionnaire in public places in two cities. A chi-squared test was conducted to compare responses for differences in proportions. RESULTS: Most participants were knowledgeable about energy requirements for moderately active men (60%) and women (59%), but underestimated energy requirements for inactive adults (34%). The majority of the respondents favored the requirement to post calorie information on menus of dine-in restaurants at the point of purchase (76%). About half the respondents (48%) were more likely to visit restaurants with labeled menus. CONCLUSION: The results from this study may form the basis for future strategies in mandating calorie labeling of restaurant menu items in UAE. Menu labeling may be a useful policy tool for promoting appropriate caloric consumption.

OBJECTIVE: To assess the physical status and feeding behavior among children with autism. METHODS: Twenty three autistic children aged 5-16 y enrolled in Sharjah Autism Center were studied. A questionnaire was administered to the parents of these children. Demographic information; gastrointestinal symptoms; mealtime behavior through Brief Assessment of Mealtime Behavior Inventory, Food Preference Inventory; and nutrient intake through a 3 day food record were collected. Physical status was determined in terms of height, weight and body mass index. RESULTS: Male-female ratio of autism in the sample was 3.6:1. Twelve children were obese and another 5 were overweight. Mealtime behavior revealed that 69.6 % of the children never/rarely cried/screamed during mealtimes, turned their face or body away from food (52 %), or expelled food (61 %) that he/she has eaten. Food Preference Inventory showed food refusal of 59.1 ± 20.6 % for combined food groups in autistic children. Specifically, higher preference was found for starches (55.8 %) and least for protein (32.6 %). A 3 day food record revealed that their diets were repetitive with limited variety and evidence of nutrient inadequacy. CONCLUSIONS: Comparatively higher enrolment of males with autism was found and three-fourth of the total children had difficulty in maintaining normal weight. Mealtime behavior concerns were displayed occasionally including rigidity in mealtime routines, unwillingness to try new foods and not being able to be seated until the meal was finished. High rates of food rejection, notably protein and limited variety resulting into nutrient inadequacy were evident.

BACKGROUND: The aim of this study was to assess the occurrence of polycystic ovary syndrome (PCOS) and its association with body composition among students in University of Sharjah (UOS). MATERIALS AND METHODS: This cross-sectional study included a total sample size of 50 female students registering in undergraduate programs at the University of Sharjah using convenience sampling technique. A pretested interview schedule was administered to elicit information pertaining to personal background and medical history related to PCOS. A diag- nostic ultrasound scan was performed for determining PCOS along with a body composition analysis using bioelectrical impedance analysis (BIA) technology. RESULTS: Twenty percent (10 out of 50 participants) were diagnosed with PCOS, of whom only 4 individuals were previously diagnosed with PCOS and aware of their conditions, while the reports showed 16% with oligomenorrhea, 4% with polymenorrhea, and none with amen- orrhea. A positive family history was indicated as reported by 22% of the total participants. Significant difference between the body weights of participants having PCOS (66.7 kg) and those without it (58.8 kg) were noted (p=0.043, t=2.084). On the other hand, the body compo- sition related variables including waist-hip ratio (WHR), fat-free mass (FFM), percent body fat (PBF) and visceral fat area (VFA) were relatively higher in participants having PCOS than those without it. However, there was no statistical significance of differences. Comparatively, the participants with PCOS had lower bone mineral density (BMD) than those without it, whereas the difference was statistically non-significant. CONCLUSION: The occurrence of PCOS in the present study is consistent with the global preva- lence. Comparatively, the body composition of PCOS females is different from the normal fe- males. Further studies are required in the Middle East region on larger sample sizes and broader aspects of health including lifestyle and dietary components to understand these differences.
