RESUMO
Objective To explore the factors related to the consumption of sugar-sweetened beverages (SSB) among middle school students in four provinces (municipality) in China.Methods A total of 3 469 middle school students were recruited from the Children health cohort in eight counties within the four provinces (municipality).We collected information regarding demography,lifestyle,and family and school situation as well as the consumption frequency of SSB in the previous week.High SSB consumption was defined as "positive" if the frequency was once a day or more.Mean consumption time was calculated,and then logistic regressions were performed to explore the factors influencing SSB consumption.Results Prevalence of high SSB consumption was 11.18％ among the subjects of the eight counties,and the consumption frequency of SSB was 0.21 times per day.Multivariate logistic regression analysis revealed that the following factors were associated with high consumption of SSB:higher grade,rural region,male gender,physical exercise,habit of eating snacks,eating out,and fast-food consumption (P＜0.01).Factors influencing high SSB consumption were not completely equal between genders:physical exercise at school was associated with high SSB consumption only in female students (P＜0.01),while higher grade and eating out in the past week were associated with high SSB consumption only in male students (P＜0.05).Conclusion Factors associated with high SSB consumption among middle school students included grade,region,physical exercise at school,snack consumption,eating out,and fast-food consumption.These factors differed between genders.Intervention programs addressing these factors may be beneficial in reducing SSB consumption in middle school students.
RESUMO
Objective To explore the influencing factors of high risk osteoporosis (OP) population. Methods Using multi-stage cluster sampling method, 1 district was selected from each of the 6 cities randomly, then 3 communities were selected from each district randomly. Questionnaire investigation and physical examination were applied to community residents aged 40-69 years old. The questionnaire mainly included basic information, OP risk assessment (using the 1 minute test method developed by the International OP Foundation), health status and lifestyle information (recent 12 months). The relationship between high-risk groups and influencing factors was analyzed by unconditional logistic regression. Results Totally 6577 valid questionnaires were collected, 2069 were male (31.46％) and 4508 were female (68.54％). A total of 166 cases (2.52％) were found as self-reported OP patients at the age of 40-69, self-reported rate of male (1.55％) was lower than that of female (2.97％) (χ2=11.719, P5000 (OR=1.336) and BMI>24.00 (OR=1.322), they were all related to a increased proportion of high risk population. Conclusion The proportion of OP high-risk groups is higher among people aged 40-69. Gender, age, cultural level, occupation, bad health status and lifestyle changes are closely related to higher OP risk. Community residents OP screening should be continued to further study the risk factors of OP.
