Abstrak: Objective: : The purpose of this study was to identify associations between suicide ideation and indicators of psychological distress and health behaviors in Chinese and Philippine adolescents.

Method: Global School Health Surveys consisting of 9015 Chinese and 7338 Philippine students aged 11 to 17 years were analyzed using logistic regression to determine demographic, psychosocial, and health/risk behavioral determinants of suicide ideation.

Results: : In both samples, suicide ideation was associated with substance use, physical activity, feelings of loneliness, hopelessness/sadness, and worrying. Chinese girls were more likely than boys to report suicide ideation and suicide planning, whereas Philippine girls were more likely to report suicide planning. Overweight status and sedentary behaviors were associated with increased risk of suicide ideation in Chinese adolescents, but the same influences were observed to be protective for Philippine adolescents.

Conclusions: : Psychosocial, demographic, and health/risk behaviors factors appear to impact suicide ideation and suicide planning in both of these youth populations.

Abstrak: Adolescent diet may be etiologically relevant for colorectal carcinogenesis. We examined the association between meat and fish intakes during adolescence and the risk of colorectal adenomas later in life among 19,771 women participating in the Nurses' Health Study II. Subjects had completed a validated food frequency questionnaire in 1998 (when aged 34-51 years) about their diets during high school and subsequently underwent at least 1 lower-bowel endoscopy during the study period (1998-2007). During this period, 1,494 subjects were diagnosed with colorectal adenomas. Intake of red meat during adolescence was not associated with colorectal adenoma risk when comparing those in the highest versus lowest category of intake (odds ratio (OR) = 1.04, 95% confidence interval (CI): 0.81, 1.35). Similarly, intake of fish during adolescence was not associated with colorectal adenoma risk (OR = 0.96, 95% CI: 0.78, 1.17). Intake of poultry during adolescence was associated with a lower risk of total colorectal (OR = 0.80, 95% CI: 0.64, 0.99), distal (OR = 0.71, 95% CI: 0.51, 0.99), rectal (OR = 0.51, 95% CI: 0.29, 0.90), and advanced (OR = 0.60, 95% CI: 0.38, 0.93) adenomas. Replacement of 1 serving per day of red meat with 1 serving per day of poultry or fish was associated with 41% and 35% decreased risks for rectal adenomas and advanced adenomas, respectively. Our findings do not suggest an association between red meat intake during adolescence and colorectal adenomas later in life, but higher poultry intake during this time was associated with a lower risk of colorectal adenomas.
