Background People worldwide have a high intake of caffeine. Active adults are among the group of people who have always been interested in caffeine as an ergogenic aid. This study aims at examining the association between caffeine consumption and perceived performance (aerobic and anaerobic exercises) among active people attending different gyms in Tripoli, Lebanon. Methods A cross-sectional study was conducted on 206 participants attending seven gyms in Tripoli. Participants were recruited using simple random sampling for a face-to-face individual interview. Data were collected using a semi-structured questionnaire. Data have been coded, entered, and analyzed using SPSS software. Results The prevalence rate of active people practicing both aerobic and anaerobic exercises is 63.6%. More than half of our sample (54.8%) has been working out for a duration of more than 6 months and 84.6% of respondents spend at least 30 min during their workouts. Caffeine consumption was popular in our sample with 92.2% indicating that they use caffeinated products. The findings of this study showed an association between anaerobic exercise and caffeine, perceived as physical performance enhancer and work durability enhancer. Yet no association was found between aerobic exercise and caffeine consumption. Conclusions Perhaps, future research could focus on the safe doses of caffeine that could be given for anaerobic exercises to have an ergogenic effect. This could help us to build scientific guidelines for caffeine’s association with sports performance.

Background. Obesity is a major health problem worldwide. Today, bariatric surgery is considered as the last option and most effective treatment for severe obesity (BMI ≥40 kg/m2 or BMI ≥35 kg/m2 with metabolic conditions). Aims. We aimed to evaluate the medium-term effect (>36 months) of bariatric surgery and assess postbariatric nutritional and lifestyle management among Lebanese patients who underwent bariatric surgeries in Jbeil and Keserwan hospitals. Methods. This study is a quantitative case-control study. The case group includes a couple of patients who have undergone sleeve or bypass surgery 6 months ago and above, along with the main family caregivers. The control group constitutes a couple of obese patients with BMI ≥30 kg/m2 who did not proceed to any surgical intervention with their main caregivers. The final samples consisted of 53 cases and caregivers and 50 controls and caregivers. The assessment was made by an online questionnaire. Results. Compared to obese patients, bariatric patients were less likely to have high energy intake (54% versus 34%, P value 0.012). Moreover, 35.8% of the caregivers of bariatric patients had a low physical activity level compared to those of the control group who had a lower level (70%). In addition, cases’ main caregivers (75.5%) had much higher quality of life compared to the cases (56.6%), and also, higher quality of life was seen among the case’s main caregivers (75%) compared to the controls (72%). Conclusion. In Jbeil and Keserwan regions of Lebanon, there is a lack of postbariatric nutritional and lifestyle management leading to less desirable outcomes in the medium to long term. A set of recommendations are developed based on this study.

Background The objective of this cross-sectional study was to evaluate the relationships between night shift work, eating habits and body mass index (BMI) among Lebanese nurses. Methods A total of 307 nurses were randomly selected from five hospitals located in Beirut. Data about demographic and professional characteristics, anthropometric measures, dietary habits and intakes were collected through a validated questionnaire. To study the relationship between night shift work, eating habits and BMI, chi-square test, t-test and logistic regressions were used. Results The majority of nurses (78. 2%) had irregular meals timing with a significant decrease in the number of complete meals consumed during the day and an increase in the number of snacks consumed during night (p r = 0.175; p r = 0.135/p Conclusion Night shift work is positively associated with abnormal eating patterns and BMI among Lebanese nurses. However the increase in BMI is not related to eating habits.

Pregnancy, this particular moment in the life of a woman, requires monitoring of eating behaviour changes. However the food choices during pregnancy should be healthy, including the consumption of different food groups, and nutritional status is the process of acquisition and consumption of food. So a varied diet is associated with good nutritional status. This is why the nutrition education is a strategy commonly applied to improve maternal nutrition during pregnancy. Therefore, it is crucial to assess "the eating behaviour and nutritional status of pregnant women living in Keserwan." The purpose of this study is to evaluate the feeding behaviour, nutritional status and level of awareness of pregnant women residing in Keserwan. A cross-sectional descriptive study is carried out, two main types of research instruments. A questionnaire containing socio-demographic, personal information, questions on eating behaviour, food frequency and nutritional education. As well as laboratory tests already done by pregnant women. The total sample surveyed included 150 pregnant women between the ages of 18 and 40 years randomly selected from the hospitals and clinics of the Keserwan gynaecologists and allocated in an equitable manner between two regions chosen according to altitude. The final analysis led to the results obtained 48.7% of pregnant women are aged 30 to 40 years, 56% have a normal BMI between 18.5 and 24.9, 80.7% have acceptable food behaviour, 68% have an acceptable level of awareness and half have an acceptable nutritional status. Thus, age affects the eating behaviour, so more women that are pregnant are older plus they have good eating behaviour. It would be possible to institute an awarenessraising program in the aim of increasing the level of education of pregnant women with regard to eating behaviour and nutritional status.

Studies have shown that frequent breakfast skipping is associated to overweight and obesity problems. The habit of skipping breakfast is increasing among adolescents. The objective of this study is to determine the prevalence of breakfast skipping among adolescents living in Lebanon. Data was collected from 404 adolescents, located in three Lebanese districts. Anthropometric measurements through calibrated equipments and dietary intake were collected by a validated food frequency questionnaire (FFQ), sociodemographic and lifestyle information were obtained by a pre-tested questionnaire, in addition BMI for age was used to determine obesity. Linear and ANOVA regressions were used to assess the association between breakfast and BMI-for-age. Six definitions of breakfast skipping were used and the prevalence varied between 8.4% and 42.8%. Linear regression was used to test the association between breakfast skipping and BMI for age. Skipping breakfast was correlated with school type, parental preparation of food, sleeping duration, milk consumption and eating meals. The association between breakfast and BMI-for-age could not be settled due to the absence of a standard definition of breakfast skipping. Our findings could not confirm a relation between breakfast and BMI-for-age. Nevertheless, skipping breakfast was related to many factors. Encouraging breakfast could be efficient for the enhancement of health. New research could be settled to find reasons for obesity and to limit its impact on adolescents living in Lebanon.
