Excessive maternal weight gain patterns in adolescents.

The objective of this study was to examine the correlates of excessive maternal weight gain among adolescent mothers in the United States. Data from the Centers for Disease Control & Prevention 2000 natality file were analyzed to examine weight gain among adolescents (< or=19 years) compared with their older counterparts (> or=20 years). Using the Institute of Medicine guidelines, we defined excessive weight gain as more than 40 pounds. Our study population was restricted to singleton births, delivered after 36 weeks of gestation, who did not live in California. Maternal weight gain distributions were tabulated by maternal age and other maternal characteristics. Demographic characteristics potentially associated with maternal weight gain were compared for adolescents and older mothers. We further evaluated the role of parity and maternal race on the relationship between excessive weight gain and maternal age. Odds ratios and 95% confidence intervals were estimated using logistic regression. Over 27% of adolescent mothers gained excessive weight during pregnancy, although approximately 18% of their older counterparts gained more than 40 pounds. The association between young maternal age and weight gain was stronger for primiparous women than multiparous women and stronger among non-Hispanic white and non-Hispanic black mothers than Hispanic mothers. Adolescents were more likely to gain excessive weight than their older counterparts in nearly all demographic categories, regardless of parity or race. Adolescents are at high risk of gaining an excessive amount of weight during pregnancy and should be monitored during pregnancy by dietetics professionals.

Use of medication prescribed for emotional or behavioral difficulties among children aged 6-17 years in the United States, 2011-2012.

Mental health problems are common chronic conditions in children (1-3). Medication is often prescribed to treat the symptoms of these conditions (4-7). Few population-based studies have examined the use of prescription medication to treat mental health problems among younger as well as older school-aged children (8-10). This report describes the sociodemographic characteristics of children aged 6-17 years prescribed medication or taking medication during the past 6 months for emotional or behavioral difficulties, and describes parental reports of the perceived benefit of this medication.

Trends in allergic conditions among children: United States, 1997-2011.

Allergic conditions are among the most common medical conditions affecting children in the United States (1-5). An allergic condition is a hypersensitivity disorder in which the immune system reacts to substances in the environment that are normally considered harmless (6,7). Food or digestive allergies, skin allergies (such as eczema), and respiratory allergies (such as hay fever) are the most common allergies among children. Allergies can affect a child's physical and emotional health and can interfere with daily activities, such as sleep, play, and attending school (8,9). A severe allergic reaction with rapid onset, anaphylaxis, can be life threatening. Foods represent the most common cause of anaphylaxis among children and adolescents (10,11). Early detection and appropriate interventions can help to decrease the negative impact of allergies on quality of life (6). This report presents recent trends in the prevalence of allergies and differences by selected sociodemographic characteristics for children under age 18 years.

Participation in activities outside of school hours in relation to problem behavior and social skills in middle childhood.

BACKGROUND: Research has shown that participating in activities outside of school hours is associated with lower dropout rates, enhanced school performance, improved social skills, and reduced problem behaviors. However, most prior studies have been limited to small populations of older children (>12 years). This analysis focuses on children aged 6 to 11 to assess the potential association between participation in activities outside of school hours and behavior in middle childhood in a nationally representative survey. METHODS: Estimates were based on 25,797 children from the 2003-2004 National Survey of Children's Health. Outside of school activity was defined as participating in sports teams/lessons, clubs/organizations, or both at least once in the past year. Analysis of variance was used to evaluate the differences in behavior problems and social skills adjusting for sociodemographic factors, among children classified by participation in outside of school activities. RESULTS: Seventy-five percent of children participated in outside of school activities: 23% in sports, 16% in clubs, and 36% in both clubs and sports. Activity participation differed by gender, race/ethnicity, type of school, poverty status, family structure, household education, and school and community safety. Children participating in both sports and clubs had higher social skills index scores, but no significant difference in problem behavior scores compared with children who did not participate in any outside of school activity. CONCLUSION: Children participating in both sports and clubs had greater social competence during middle childhood compared with children who did not participate in any outside of school activities.
