Longitudinal Changes in Weight Status from Childhood and Adolescence to Adulthood.

OBJECTIVES: To study the change in body mass index (BMI) from childhood and adolescence and development of obesity into adulthood. STUDY DESIGN: We performed a longitudinal study of 480 individuals (49% male; 67% white) with height and weight measures in childhood (mean age 7 years), repeated in adolescence (mean age 16 years) and adulthood (mean age 39 years). Weight status in childhood was defined as low normal weight (0-<50 BMI percentile); high normal weight (50-<85 BMI percentile); overweight (85-<95 BMI percentile); obese (≥95 BMI percentile). Adult weight status was defined as normal weight (18.5-<25 kg/m2); overweight (25-<30 kg/m2); obese (>30 kg/m2). RESULTS: Adult obesity (%) increased with weight status in childhood (low normal weight 17%; high normal weight 40%; overweight 59%; obesity 85%) and similarly with adolescence. Children in a lower category in adolescence than in childhood had lower risk of having adult obesity than did those who maintained their childhood category. Among adults with obesity, 59% (111 out of 187) were normal weight as children, with 75% (83 out of 111) from the high normal weight children; and 50% of adults with obesity were normal weight (n = 94/187) as adolescents, with 84% (81 out of 94) from the high normal weight adolescents. Only 6% of 143 normal weight adults had either overweight (n = 9) or obesity (n = 0) during childhood. CONCLUSIONS: This study shows the high risk for adult obesity in children and adolescents who have overweight or obesity. A majority of adults with obesity had a 50-85 BMI percentile as children. Those who did not move to higher weight status between childhood and adolescence had lower probability of adult obesity.

Implementation of lipid screening guidelines in children by primary pediatric providers.

OBJECTIVE: To assess the awareness and implementation of lipid guidelines among primary pediatric providers. STUDY DESIGN: An online survey was administered to primary pediatric providers (n = 1488): pediatricians, family medicine/general practitioners, and advanced practitioners (nurse practitioners/physician assistants) in Minnesota. The survey was conducted over 12 weeks in 2012-2013. A multiple-choice questionnaire was used to evaluate the participants' knowledge, screening, and management attitudes regarding pediatric lipid guidelines. RESULTS: The overall response rate was 39% (n = 548 of 1402 successful e-mails). Respondents were primarily pediatricians and family medicine practitioners (37% each), followed by general practitioners (11%) and advanced practitioners (nurse practitioners, 5.5%; physician assistants, 1.6%). Although 74% of providers reportedly believed that lipid screening and treatment would reduce future cardiovascular risk, 34% performed no screening, 50% screened selectively, and only 16% performed universal screening. Pediatricians were more likely to screen, with 30% performing universal screening and 41% performing selective screening. Among perceived barriers to screening, providers reported uneasiness addressing lipid disorders (43%), and unfamiliarity with screening guidelines (31%). The majority (83%) were uncomfortable managing lipid disorders, and 57% were opposed to the use of lipid-lowering medications in children. CONCLUSION: These findings underscore the need to further educate providers and supply easily accessible information on the screening and treatment of childhood lipid disorders.
