Fine Particulate Matter (PM(2.5)) Air Pollution and Selected Causes of Postneonatal Infant Mortality in California
Studies suggest that airborne particulate matter (PM) may be associated with postneonatal infant mortality, particularly with respiratory causes and sudden infant death syndrome (SIDS). To further explore this issue, we examined the relationship between long-term exposure to fine PM air pollution and postneonatal infant mortality in California. We linked monitoring data for PM ā¤2.5 Ī¼m in aerodynamic diameter (PM(2.5)) to infants born in California in 1999 and 2000 using maternal addresses for mothers who lived within 5 miles of a PM(2.5) monitor. We matched each postneonatal infant death to four infants surviving to 1 year of age, by birth weight category and date of birth (within 2 weeks). For each matched set, we calculated exposure as the average PM(2.5) concentration over the period of life for the infant who died. We used conditional logistic regression to estimate the odds of postneonatal all-cause, respiratory-related, SIDS, and external-cause (a control category) mortality by exposure to PM(2.5), controlling for the matched sets and maternal demographic factors. We matched 788 postneonatal infant deaths to 3,089 infant survivors, with 51 and 120 postneonatal deaths due to respiratory causes and SIDS, respectively. We found an adjusted odds ratio for a 10āĪ¼g/m(3) increase in PM(2.5) of 1.07 [95% confidence interval (CI), 0.93ā1.24] for overall postneonatal mortality, 2.13 (95% CI, 1.12ā4.05) for respiratory-related postneonatal mortality, 0.82 (95% CI, 0.55ā1.23) for SIDS, and 0.83 (95% CI, 0.50ā1.39) for external causes. The California findings add further evidence of a PM air pollution effect on respiratory-related postneonatal infant mortality

Childrenās, Their Guardiansā, and Health Care Professionalsā Perceptions of Child Overweight in Relation to Childrenās Weight Loss Attempts
Purpose: To examine accuracy of children\u27s, their guardians\u27, and health care professionals\u27 (HCPs\u27) perceptions of child overweight and obesity, the degree of agreement between their perceptions, and relationships with weight loss attempts among overweight or obese children.
Design: Cross-sectional study using 2005ā2010 National Health and Nutrition Examination Survey.
Setting: United States.
Subjects: Out of 4691 children and adolescents, ages 8 to 15 years, 16.4% were overweight (body mass index [BMI] percentiles 85ā94.99) and 19.3% were obese (BMI percentiles ā„95).
Measures: Age and sex-specific BMI percentiles; responses of adult proxies (guardians) on whether they considered their child overweight and whether an HCP had ever told them that their child was overweight; responses of children and adolescents on their self-perceived weight status and whether they were trying to lose weight; children\u27s and guardians\u27 socio-demographic characteristics.
Analysis: Weighted percentages; sensitivities and Cohen\u27s kappas; adjusted prevalence ratios.
Results: Children, their guardians, and HCPs underestimated child\u27s actual overweight or obesity status. Little agreement existed between overweight or obese children, their parents, and HCPs on whether these children were overweight or obese. Overweight and obese children perceived as such by themselves, their guardians, and HCPs were 88% and 32%, respectively, more likely to attempt weight loss based on multivariable analyses.
Conclusion: Accurate and shared perceptions of adiposity in children and adolescents between children themselves, their guardians, and HCPs are positively associated with weight loss attempts among overweight or obese children in the United States
