In this study, we use a narrative format to review the evidence for a prospective association with adiposity and other well-established biological cardiovascular risk factors in healthy young people, considering only studies with at least 2 years of follow-up. PA appears to elicit a long-term beneficial effect on adiposity and particularly markers of cardiovascular health. With adiposity, however, a few studies also reported that higher levels of PA were associated with higher levels of adiposity. Time spent sedentary does not appear to be related to adiposity or markers of cardiovascular health independent of PA. We then discuss the uncertainties in the underlying causal chain and consider a number of alternative modeling strategies, which could improve our understanding of the relationship in future studies. Finally, we consider the current methodology for assessing PA and sedentary time.展开更多

Questions derived from the prevalidated scales were used to measure the IPV. Questionnaires were distributed to both men and women aged from 18 to 60. The participants were staff and students of University of Goroka, staff of the Goroka Secondary school and North Goroka Primary school, Teachers in-charges of the elementary schools in the Eastern Highlands Province and the villagers from Asaroufa and Kotuni villages. Of the 95 respondents, 78.95% were victims of IPV. Among the victims 37.33% were males and 62.67% females. The physical, sexual and psychological abuses were experienced by both men and women. The significant risk factors found to be associated with violence were young age, low education, low socioeconomic status, marital conflicts, history of abuse during childhood, and male patriarchal values. The interpersonal relationship tends to be an important factor for prevailing violence free environment within the intimate partners. Intimate partner violence is prevalent in PNG. The strongest independent predictors were the excessive drinking of alcohol and marital conflict. Preventive measures such as compulsory and free technical education for all children less than 14 years old and life skills training and violence awareness campaign for both men and women must be provided to reduce the intimate partner violence.展开更多
