Research findings on parental communication about sex have been mixed and inconclusive. Attempts to synthesize findings are complicated by different research methods, very different measures of parent-adolescent communication, and different perceptions of various groups. Inconsistent and contradictory findings may arise from a lack of standard measurements across studies. Existing studies on parent-child communication about sex have several limitations. First, numerous studies have been undertaken with white adolescents. Furthermore, the results of the few studies focused on ethnic groups have found inconsistent results. Hovell et al. (1994) and Hutchinson (2002) compared the amount of parent-child communication about sex across ethnic groups and found that Latino families communicate less generally and about sex-specific issues than families of other ethnic groups. Furthermore, numerous studies of parent-child communication about sex have focused not only on specific sexual topics, but also on global communication (Feldman & Rosenthal, 2000). When specific sexual topics were addressed, however, rates of discussion of each individual topic varied widely (Jaccard et al., 1998). Furthermore, parent-child communication has often been examined by self-reports generally only from the adolescents' perspective. Even when research has focused on couples or parents' perspectives, agreement or disagreement between reports of such communication has rarely been addressed. Many studies focusing on how adolescents and parents report conversations found that most mothers believed they discussed sex more than their adolescents perceived (Chung et al., 2007). Finally, numerous studies have focused on the frequency... .... middle of the paper ......Wamoyi et al. (2010), Tanzanian parents demonstrated that HIV/AIDS was the one thing they often talked about with their children because it was considered shameful and was an illness associated with extreme suffering. Two studies on parents' attitudes and perceptions regarding the content of discussions on sex revealed that Greek parents perceive that the most important topic for parents' sexual education towards their adolescents is AIDS and sexually transmitted diseases communicable (37%), the second priority is contraception and the third is relationships. The issue of abortion was the fourth priority (Kirana et al., 2007). Nigerian parents perceived that the most important topic parents should provide to their children was life and relationship skills, the second priority was sexual health such as sexually transmitted infections, and the third priority was personal hygiene ( Akinwale et al..,2009).
