Objective: To explore the prevalence of elevated blood pressure and overweight/obesity and their comorbidities among Tibetan middle school students in Lhasa, and to analyze their association with lifestyle and other factors, so as to provide a basis for the intervention measures targeting elevated blood pressure, overweight and obesity among middle school students in high altitude area. Methods: Using a stratified cluster random sampling method in September 2021, a total of 1 488 Tibetan junior and high students from Lhasa City were investigated with blood pressure measurement, physical examination and questionnaire survey. The influencing factors of elevated blood pressure, overweight and obesity and their comorbidities association were analyzed by multivariate Logistic regression. Results: The prevalence of elevated blood pressure, overweight/obesity and their comorbidities were 17.8%, 17.4% , 5.0% respectively. Multivariate Logistic regression analysis showed that age( OR =0.81), residence, body mass inex(BMI) and gender were the influencing factors of elevated blood pressure; and the risks of elevated blood pressure in female students were higher than male students ( OR =1.89), suburban students were higher than urban students ( OR =8.06), overweight and obesity groups were higher than normal groups ( OR =2.55, 2.87) ( P <0.05). Adjusting for confounding factors such as gender, residence and school, and BMI (only for elevated blood pressure), daily screen time ≥2 h was positively correlated with elevated blood pressure, overweight/obesity and its comorbidities ( OR =1.56, 1.59 , 2.51) ( P <0.05). Conclusions The prevalence of elevated blood pressure, overweight/obesity are relatively high in Lhasa. Longer screen time is a common factor affecting with elevated blood pressure, overweight/obesity and comorbidities among Tibetan students. Measures should be taken intervene in the lifestyle of Tibetan students, in order to reduce elevated blood pressure and overweight/obesity.

BACKGROUND/OBJECTIVES: The specific impact of different fruit and vegetable consumption categories on frailty is not completely understood. This study examined the relationships between the daily consumption of fruit and vegetables and frailty in a large general population. SUBJECTS/METHODS: This study used the data from the US National Health and Nutrition Examination Survey (2005–2020). Two intermittent 24-h dietary recalls were used to evaluate fruit and vegetable consumption. Frailty was assessed using the frailty index. Logistic regression, stratified analyses, and restricted cubic spline models were used to examine these associations. RESULTS: A higher daily intake of citrus, melons, and berries (odds ratio [OR], 0.77; 95% confidence interval [CI], 0.65–0.92), other fruit (OR, 0.74; 95% CI, 0.62–0.88), intact fruit (OR, 0.71; 95% CI, 0.60–0.84), dark-green vegetables (OR, 0.71; 95% CI, 0.60–0.83), and total vegetables (OR, 0.80; 95% CI, 0.66–0.96), along with a lower fruit juice intake (OR, 0.81; 95% CI, 0.69–0.96), were associated with a reduced risk of frailty in adults aged 18 yrs and older.Further analysis showed that the daily consumption of citrus melons and berries, other fruit, intact fruit, fruit juice, and tomatoes and tomato products were inversely associated with frailty in adults under 60 yrs and females. Dark green vegetables were inversely correlated with frailty in individuals aged 40–60 yrs and over 60 yrs, regardless of sex. CONCLUSION The daily consumption of most types of fruit, dark green vegetables, and tomatoes and tomato products may reduce the risk of frailty in American adults, particularly for individuals under 60 yrs of age and females.
