The same applies to active disclosure to their children (score in the subscale intrusion: 17.8. vs. 21.4; p=.02 and score in the subscale hyperarousal: 19.5 vs. 24.5; p=.01). Disclosure to parents and to grandchildren is not connected with lower PTSD symptoms. Conclusion: The results provide evidence that the concrete receiver of the disclosure in the family should be taken more into consideration. Future research on effects of disclosure should observe that. Objective: To compare smoking rates among girls and young women in seven ASEAN countries (Cambodia, Indonesia, Lao PDR, Malaysia, Philippines, Thailand and Vietnam) and sociocultural factors associated with it. Methods: A regional study on smoking among females was conducted in 2007/08. A quasi-random sample of about 3,000 female respondents between the ages of 13 and 25 from secondary schools and colleges/universities from the capital city of each country together with one rural district was surveyed using a standardized self-administered structured questionnaire. Each country data set was processed and analyzed using SPSS version 12. Logistic regression analysis was used to determine sociocultural factors significantly associated with current smoking (in the last month).
