Gendered differences in the predictors of sexual initiation among young adults in Cebu, Philippines.

PURPOSE: Social environment and family context exert substantial influence on adolescent sexual behaviors. These influences are especially important to examine in countries undergoing rapid demographic and social change. This study employs unique, intergenerational and longitudinal data (1998-2009) to examine the effects of parental, peer, and household influences on sexual initiation among young adults in Cebu, Philippines. METHODS: Intergenerational and longitudinal cohort data from the 1998 Cebu Longitudinal Health and Nutrition Survey (CLHNS) are analyzed to examine the effects of household, peer, family, and young adults' sexual attitudes on age at first sex by 2009 among young men and women. Gender-stratified Cox proportional hazards models and Cox regression models are used to model time to first sex. RESULTS: Household, family, peer, and individual characteristics have disparate influences on sexual initiation among Filipino boys and girls. Boys' sexual initiation was positively associated with urbanicity, household wealth, and the presence of a family member working abroad, whereas for girls, these variables had no significant effects. Unique effects were also found for girls-mother's education was negatively associated, and girls' number of siblings was positively associated, with higher hazards of sex. Additionally, the effects of some variables on the occurrence of first sex differed across time, indicating that boys and girls may be differentially influenced by contextual characteristics across adolescence. CONCLUSIONS: Amid substantial sociodemographic changes and persistence of traditional gender norms, this study highlights the importance of examining the unique influences and intersections of gender and context on sexual initiation in the Philippines.

Waist circumference and the risk of hypertension and prediabetes among Filipino women.

OBJECTIVES: To examine waist circumference as a risk factor for having hypertension only, impaired fasting glucose only, or both hypertension and impaired fasting glucose, and assess whether the associations vary according to overweight status. Furthermore, optimal cut-offs for waist circumference in overweight women and non-overweight women were explored. DATA AND METHODS: Data from 1,871 women aged 35-68 years in the 2005 Cebu Longitudinal Health and Nutrition Survey were used. Multinomial logistic regressions were used to model how waist circumference influenced the likelihood of having the three illness categories compared to having neither condition. Waist circumference cut-offs were explored using receiver operating characteristic analysis. RESULTS: Adjusted for age and other confounders, each cm increase in waist circumference increased the odds of hypertension by 5 % for non-overweight women and 3 % for overweight women; impaired fasting glucose by 9 and 3 % for non-overweight and overweight women, respectively; and hypertension and impaired fasting glucose by 17 % among non-overweight versus 9 % for overweight women. Waist circumference cut-offs for non-overweight women were lower than overweight women. CONCLUSION: Waist circumference was significantly associated with impaired fasting glucose and both hypertension and impaired fasting glucose, and the associations vary by overweight status.

Old ideals and new realities: the changing context of young people's partnerships in Cebu, Philippines.

The Philippines has experienced rapid sociodemographic changes in recent years, with implications for young people. This study combines quantitative and qualitative data from Metro Cebu to assess the timing and predictors of young people's partnerships, as well as the context in which these partnerships are occurring. The majority of young people (54%) had premarital sex, though this pattern varied by gender. Wealthier, urban young men, and women with less education and lower reported religiosity, were more likely to have premarital sex. Engagement in risk behaviours was predictive of premarital sex for both males and females. The qualitative data contextualise the circumstances under which young people engage in sex and form partnerships and illustrate how sociocultural norms contribute to gender differences in partnership patterns. Given the 'new' realities of young Filipinos' lives, targeted efforts to support the transition to adulthood are needed to avert potentially adverse life events.
