During the last few decades, the Kingdom of Saudi Arabia (KSA) experienced rapid socio-cultural changes caused by the accelerating economy in the Arabian Gulf region. That was associated with major changes in the food choices and eating habits which, progressively, became more and more "Westernized". Such "a nutritional transition" has been claimed for the rising rates of overweight and obesity which were recently observed among Saudi population. Therefore, the objectives of the current work were to 1) determine the prevalence of overweight and obesity in a sample of male college students in KSA and 2) determine the relationship between the students' body weight status and composition and their eating habits.

Introduction: Obesity and iron deficiency are prevalent health problems that affect billions of people all over the world. Obesity is postulated to relate to iron deficiency via reduced intestinal iron absorption due to increased serum hepcidin level, which is mediated by chronic inflammation. Weight loss in individuals with overweight or obesity and iron deficiency anemia is believed to be associated with an improvement in iron status however the evidence from clinical trials is scarce. This study was conducted to evaluate the effect of diet-induced weight loss on iron status and its markers among young women with overweight/obesity and iron deficiency anemia.Methods: The study design was a single-blinded, randomized controlled trial with two parallel arms (weight loss intervention vs control). Study participants were recruited using the convenience sampling method through public advertisements posted and disseminated through social media. Interested and potential participants were asked to visit the Diet Clinic for eligibility screening. A total of 62 women were recruited and randomized into weight loss intervention and control group. The intervention duration was three months. The intervention group received individual consultation sessions with the dietitian and tailored energy-restricted diets. Physical activity levels, dietary intake, anthropometric measurements and clinical markers were measured at baseline and end of the trial.Results: There was a significant decrease (p < 0.001) in body weight of the intervention group (-7.4 ± 2.7 kg) that was associated with significant improvements in iron status and its markers (p < 0.01). The intervention group experienced a significant increase in hemoglobin (0.5 ± 0.6 g/dL), serum ferritin (5.6 ± 5.8 ng/mL), and serum iron (13.0 ± 16.2 µg/dL), and a significant decrease in high-sensitivity C-reactive protein (-5.2 ± 5.6 mg/L), and serum hepcidin level (-1.9 ± 2.2 ng/mL) at the end of the trial.Conclusion: Our findings indicate that diet-induced weight loss among participants was associated with an improvement in iron status and its related clinical markers.Clinical Trial Registration: [https://www.thaiclinicaltrials.org/show/TCTR20221009001], identifier [TCTR20221009001].

Breakfast skipping is linked with obesity incidence. This study was conducted to assess the prevalence of breakfast skipping among a multi-ethnic population of young men residing in Saudi Arabia and its relationship with sociodemographic determinants and weight status. A total of 3600 young men aged 20 to 35 years and living in Riyadh, Saudi Arabia, were involved in this cross-sectional study. Sociodemographic determinants and breakfast-consumption frequency were collected from subjects by personal interviews. This study defines breakfast skipping as skipping breakfast at least one day per week. Weight and height were measured following standardized methods. The prevalence of breakfast skipping was observed among 52.8% of the study subjects. Nationality was a predictor of breakfast skipping, with the lowest and highest rates of breakfast skipping reported among young men from Bangladesh (14.0%) and Saudi Arabia (86.5%), respectively. Weight status was another predictor of breakfast skipping, as the mean body mass index for breakfast skippers (25.4 kg/m²) was significantly (p-value < 0.001) higher than that for breakfast consumers (24.8 kg/m²). Overweight/obese subjects have a significantly higher rate of breakfast skipping (56.9%) than underweight/normal weight subjects (48.9%). In conclusion, breakfast skipping prevalence is relatively high among young men residing in Saudi Arabia. The findings confirm a relationship between breakfast skipping and sociodemographic determinants and weight status.

Fast food is commonly consumed by young adults. Eating fast food is connected with the risk of obesity and other related diseases. The present study examines the prevalence of fast food intake in a diverse sample of young men. This cross-sectional study included 3600 young men (20–35 years) who resided in Riyadh, KSA. The frequency of fast food intake was assessed using a valid and reliable questionnaire. Weekly and daily intake of fast food were the two outcome variables adopted to assess the intake frequency. Weight and height were measured. Fast food was eaten by 88.8% and 50.1% of participants weekly and daily, respectively. Fast food intake was predicted by the nationality of participants. The highest prevalence of weekly fast food intake (99.7%) was observed among Saudi, Egyptian, and Indian participants, while the lowest rate was observed among Sudanese participants (48.6%). The highest and lowest rates of daily intake were seen among Filipino (83.4%) and Bangladeshi (6.3%) participants. Obesity was another predictor of fast food intake. Obese participants had a significantly higher odds ratio of weekly (OR = 2.89, p = 0.006) and daily (OR = 1.39, p = 0.021) fast food intake than non-overweight/non-obese participants. In conclusion, fast food is frequently consumed by young men in KSA. Our findings link the likelihood of fast food intake to sociodemographic determinants and obesity.

Purpose: This study was conducted to determine differences in overweight and obesity prevalence and the associated sociodemographic variables among middle-aged men from twelve Middle Eastern and Asian countries living in Riyadh, Saudi Arabia. Methods: This is a cross-sectional study. The study sample was chosen randomly using a stratified clustered sampling technique. The weight and height of 1800 middle-aged men (36 to 59 years) from twelve Middle Eastern and Asian countries living in Riyadh, Saudi Arabia, were measured using standardized methods. Face-to-face interviews were used to gather sociodemographic information from participants. Results: Overweight and obesity were reported among 51.9% and 14.7% of participants, respectively. Nationality was a predictor of overweight and obesity. Subjects from Bangladesh and Saudi Arabia had the lowest (41.0%) and highest (85.1%) rates of overweight and obesity, respectively. Increasing age, staying in Saudi Arabia for a longer period, being single, and earning a high monthly income were associated with a significantly higher risk of overweight and obesity among the participants. Conclusion: The findings revealed significant differences in the prevalence of overweight and obesity among participants from different countries living in Saudi Arabia. Sociodemographic variables associated with overweight and obesity among participants were identified.

Sugar-sweetened beverages are frequently consumed among adults and are linked with the incidence of obesity. We aimed to determine rates of weekly and daily sugar-sweetened beverage intake in a multi-ethnic population of young men and their association with sociodemographic characteristics and obesity. This cross-sectional study included 3600 young men who lived in Riyadh, KSA. Participants’ sociodemographic characteristics and frequency of sugar-sweetened beverage consumption were gathered through personal interviews. The outcome variables in this study are based on the weekly and daily consumption of sugar-sweetened beverages. Weight and height were measured following standard protocols. The rates of weekly and daily sugar-sweetened beverage intake by participants were 93.6% and 40.8%, respectively. Nationality was a predictor of weekly and daily consumption of sugar-sweetened beverages. The highest rates of weekly (99.5%) and daily (63.9%) consumption were observed in subjects from the Philippines and Yemen, respectively, while Bangladeshi subjects had the lowest rates of weekly (76.9%) and daily (6.9%) consumption. Obesity was another predictor of sugar-sweetened beverage consumption. Obese participants had a significantly higher odds ratio of weekly sugar-sweetened beverage consumption than non-obese subjects (OR = 4.53, p = 0.037). In conclusion, sugar-sweetened beverage consumption was relatively high and our results support an association between the consumption of sugar-sweetened beverages and certain sociodemographic variables and obesity.
