Risk factors for emotional/behavioral problems in young adolescents: a prospective analysis of adolescent and parental stress and symptoms.

Stressful events in the lives of 309 10- to 15-year-olds and stressful events and psychological symptoms reported by their parents were examined in a 9-month study. Ss' self-reported emotional/behavioral problems were predicted by their reports of stressful events and their fathers' reports of psychological symptoms in cross-sectional analyses. Analyses at follow-up after controlling for initial reports of emotional/behavioral problems and prospective analyses predicting from first assessment to follow-up yielded significant effects for Ss' self-reported stressful events. Mothers' reports of children's problems were predicted by mothers' psychological symptoms in cross-sectional analyses and at follow-up after controlling for initial emotional/behavioral problems. Only prior levels of maternal reports of emotional/behavioral problems predicted mothers' reports of their children's problems 9 months later.

Adolescent drug use in Mexico and among Mexican American adolescents in the United States: environmental influences and individual characteristics.

The authors compared high school students in Baja California Norte (BCN), Mexico (n = 775), with Mexican American students in Los Angeles (LA), California (n = 516). The students' use of cigarettes, alcohol, marijuana, cocaine, inhalants, and other illicit drugs were compared, because these vary by gender, country, and their age of first drug use and are influenced by demographic variables, individual characteristics, and environmental influences. More BCN students than LA students had used alcohol, but more LA than BCN students had used illicit drugs and initiated drug use earlier. When demographic variables were influential, they were most powerful and increased the risk for drug use more than environmental factors or individual characteristics. Environmental factors were most influential for boys' drug use, whereas environmental and demographic variables were most influential for girls' drug use.

Adolescent girls and their babies: achieving optimal birthweight. Gestational weight gain and pregnancy outcome in terms of gestation at delivery and infant birth weight: a comparison between adolescents under 16 and adult women.

AIMS: Pregnancy amongst under 16s has been reported to result in worse outcomes for the baby, including low birthweight. This study aimed to find out whether the under 16s need to gain more weight during pregnancy to avoid this outcome. METHOD: A retrospective case control study of pregnancy outcomes in girls delivering before the age of 16 and women delivering aged 25-30. Data was collected from medical case notes, including maternal age, pregnancy weight gain and infant birth weight. RESULTS: Although weight gain amongst under 16s was similar to that in the control group, average birthweight of babies born to under 16s was less than in the older group. For both girls and older women greater weight gain in pregnancy did result in higher birth weights. DISCUSSION: As younger girls are still growing it may be necessary for them to achieve a greater pregnancy weight gain in order to achieve a satisfactory birth weight.

Prevalence of primary HIV-1 drug resistance among recently infected adolescents: a multicenter adolescent medicine trials network for HIV/AIDS interventions study.

This study examined the prevalence of primary human immunodeficiency type 1 (HIV-1) drug resistance among recently infected youth in the United States. Of the 55 subjects studied, major mutations conferring HIV drug resistance were present in 10 (18%). Eight (15%) had nonnucleoside reverse-transcriptase inhibitor (NNRTI) mutations, with the majority (6) having the K103N mutation; 2 (4%) had nucleoside reverse-transcriptase inhibitor (NRTI) mutations; and 2 (4%) had protease inhibitor (PI) mutations. Phenotypic drug resistance was present in 12 (22%) subjects: 10 (18%) for NNRTIs, 2 (4%) for NRTIs, and 3 (5.5%) for PIs. The prevalence of primary HIV-1 drug resistance, particularly to NNRTIs, in this group of recently infected youth was high.

A comparison of menstrual changes expected by pre-menarcheal adolescents and changes actually experienced by post-menarcheal adolescents in Mexico.

This survey explored para-menstrual changes that Mexican pre-menarcheal girls expect to experience and paramenstrual changes actually experienced by post-menarcheal girls. The survey included 95 pre-menarcheal girls who reported what they expected to experience in the para-menstruum, and their answers were compared with para-menstrual changes reported by 98 post-menarcheal girls. There were more post-menarcheal than pre-menarcheal girls who reported negative physical changes, while more pre-menarcheal girls expected to experience negative changes related to cognitive-emotional expressions. Regarding positive para-menstrual changes, despite the fact that hardly any of the girls named them, more post-menarcheal girls reported positive changes than pre-menarcheal girls who expected the changes. The dominant menstrual discourse concerning menstruation focused on para-menstrual negative changes, which can lead pre-menarcheal girls to anticipate their periods with fear and to overlook positive changes that may occur in the para-menstruum.
