Dietary intake is an important risk factor that contributes to the development or prevention of many health conditions. The objective of the current study was to identify different dietary patterns and its relation to socio-demographic and life-style characteristics. A cross-sectional study of 299 Saudi adults, aged between 35-65 years without any significant health problems. Participants were interviewed individually and completed a pre-designed questionnaire with close-ended questions including socio-demographic and lifestyle characteristics. Dietary intake was assessed using food frequency questionnaire. Anthropometric measurements were obtained by a trained nurse in the clinic. Factor analysis technique was used to derive different food patterns. Five dietary patterns were identified, namely: sweet & starch, date & coffee, healthy, traditional, and protein patterns. Following sweet & starch pattern was significantly correlated to male gender, frequently visiting fast food restaurants and breakfast consumption behavior. Adherence to healthy pattern was associated with male gender, higher education with high income, older adults, breakfast consumption behavior and high levels of physical activity. Traditional pattern was correlated with married subjects and male gender, whereas compliance to date & coffee pattern was related to reduced number of meals and snacks. The protein pattern was significantly associated with younger age and breakfast consumption behavior. Dietary patterns were influenced by socio-demographic characteristic (age, gender, marital status, education level, income) and other lifestyle factors (breakfast consumption, number of meals, physical activity). A national cohort study is needed to assess the association between dietary patterns with the risk of cardiometabolic dysregulation.

Obesity prevalence is rising globally, as are the number of chronic disorders connected with obesity, such as diabetes, non-alcoholic fatty liver disease, dyslipidemia, and hypertension. Bariatric surgery is also becoming more common, and it remains the most effective and long-term treatment for obesity. This study will assess the influence of Laparoscopic Sleeve Gastrectomy (LSG) on gut microbiota in people with obesity before and after surgery. The findings shed new light on the changes in gut microbiota in Saudi people with obesity following LSG. In conclusion, LSG may improve the metabolic profile, resulting in decreased fat mass and increased lean mass, as well as improving the microbial composition balance in the gastrointestinal tract, but this is still not equivalent to normal weight microbiology. A range of factors, including patient characteristics, geographic dispersion, type of operation, technique, and nutritional and caloric restriction, could explain differences in abundance between studies. This information could point to a novel and, most likely, tailored strategy in obesity therapy, which could eventually be incorporated into health evaluations and monitoring in preventive health care or clinical medicine.

To analyze the association between Fat Mass Index (FMI), Free Fat Mass Index (FFMI), Free Fat Mass/Fat Mass (FFM/FM), and Body Mass Index (BMI) among young adult Saudi women and to explore how these body composition indices are associated with sleep and physical activity patterns. A total of 1,741 university female students participated in this cross-sectional study. Body composition was measured using the InBody 270 body composition analyzer. FMI, FFMI, and FM/FFM were classified into tertiles (T1, T2, T3), with T1 classified as the lowest and T3 as the highest tertile. Sleep quality and duration were assessed using the Pittsburgh Sleep Quality Index, while physical activity was measured using an exercise vital sign tool. BMI increased significantly from Tertile 1 to Tertile 3 across all groups for FMI and FFMI (p < 0.001), while a decrease in FM/FFM was observed across tertiles (p < 0.001). Conversely, FFM was highest in the third tertile of FFMI (p < 0.001). No significant associations were found between sleep duration or quality and body composition indices, even after adjusting for age and BMI. However, significant associations were observed between physical activity frequency and duration and body composition, particularly FFMI and FMI. These associations became more pronounced after adjusting for age and BMI. The findings highlight a strong association between physical activity patterns and body composition indices, particularly FFMI and FMI, among young adult Saudi women. While sleep patterns did not show significant relationships with body composition, the results emphasize the importance of regular physical activity in maintaining healthy body composition. These insights underline the need for targeted interventions promoting physical activity to support optimal health and well-being in this population.

Bariatric surgery has significantly increased globally as an effective treatment for severe obesity. Nutritional deficits are common among candidates for bariatric surgery, and follow-up of nutritional status is critically needed for post-surgery healthcare management. This observational prospective study was conducted at King Khalid University Hospital in Riyadh. Samples were collected pre- and post-laparoscopic sleeve gastrectomy (LSG), with the visit intervals divided into four visits: pre-surgery (0M), 3 months (3M), 6 months (6M) and 12 months (12M). Food intake and eating patterns significantly changed during the first year (P < 0·001). The mean energy intake at 3M post-surgery was 738·3 kcal, significantly lower than the pre-surgery energy intake of 2059 kcal. Then, it increased gradually at 6M and 12M to reach 1069 kcal (P < 0·00). The intake of Fe, vitamin B₁₂ and vitamin D was below the dietary reference intake recommendations, as indicated by the 24-hour dietary recall. The prevalence of 25 (OH) vitamin D deficiency improved significantly from pre- to post-surgery (P < 0·001). Vitamin B₁₂ deficiency was less reported pre-LSG and improved steadily towards a sufficient post-surgery status. However, 35·7 % of participants were deficient in Fe status, with 28·6% being female at higher levels than males. While protein supplementation decreased significantly over the 12M follow-up, the use of vitamin supplements dramatically increased at 3 and 6M before declining at 12M. Fe and vitamin B₁₂ were the most popular supplements after vitamin D. This study confirms the necessity for individualised dietary plans and close monitoring of candidates’ nutritional status before and after bariatric surgery.
