Risk profiles for overweight/obesity among preschoolers.

BACKGROUND The epidemic of overweight/obesity among U.S. children has led to an alarming increase in health-related consequences, including early-onset diabetes and cardiovascular disease. Recent research has identified the independent contribution of several maternal and child factors to the development of childhood overweight/obesity. Few studies, however, have examined risk profiles of childhood obesity. AIM This study used classification and regression tree (CART) analysis to examine the combined effect of maternal and child factors in generating risk profiles for overweight/obesity among preschoolers. STUDY DESIGN Data from the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B) study were used. The sample was comprised of preschool children. CART and logistic regression models were built and compared. RESULTS Children who were overweight/obese at two years of age had an increased risk of being overweight/obese at four years of age. Children born to overweight/obese mothers were more likely to be overweight/obese by age four, even if their BMI at two years of age was normal. Children with high birth weight (> or = 4000 g.) were also more likely to be overweight/obese at age four years if they were born to mothers with a normal pregravid BMI, but were of a lower socioeconomic status. Among preschoolers whose mothers were black or white and who had a high pregravid BMI, breastfeeding duration and parity played an important role in determining their risk of being overweight/obese. CONCLUSIONS Classification tree analysis confirms and extends current knowledge of preschool overweight/obesity by providing preliminary risk profiles that are structured within the context of prenatal and postnatal maternal and child characteristics.

Clinical Practice Guidelines for Feeding Behaviors and Weight-for-Age at 12 months: A Secondary Analysis of the Infant Feeding Practices Study II

BACKGROUND The World Health Organization has identified childhood obesity as a major threat to global health. Accumulating evidence indicates that excess weight early in life is predictive of later childhood and adolescent obesity. Clinical practice guidelines for infant feeding behaviors have been developed by national and international health organizations. The relationship between these guidelines and infant weight status has not been established. AIM To examine the relationship between weight-for-age at 1 year and adherence to four clinical practice guidelines for feeding behaviors: no bottle-to-bed, minimal juice consumption, breastfeeding throughout the first year of life, and introduction to solid food no earlier than age 4-6 months. METHODS Data were obtained from the Infant Feeding Practices Study II, a longitudinal, national survey administered by the U.S. Food and Drug Administration and Centers for Disease Control and Prevention that followed mother-infant dyads from pregnancy through 1 year postpartum. The sample was comprised of 691 infants for whom 12-month survey data were available. RESULTS Significant associations with weight-for-age were found for juice consumption (p= 0.003), breastfeeding during the second half of infancy (p < 0.001), and introduction to solid foods prior to age 4 months (p < 0.001). A regression model that controlled for infant and maternal characteristics demonstrated that these feeding behaviors remained significant predictors of weight-for-age at 12 months. CONCLUSIONS AND IMPLICATIONS Modifiable infant feeding behaviors contributed to weight-for-age at 1 year. Replication studies with economically and culturally diverse samples are needed. Further, testing longitudinal interventions that address infant feeding practices is likely to yield the evidence needed for shaping future clinical practice guidelines that reduce the risk for childhood obesity and related pediatric comorbidities.

Postpartum Depression, Infant Feeding Practices, and Infant Weight Gain at Six Months of Age

INTRODUCTION This study examined postpartum depression (PPD) as a potential risk factor for non-adherence to infant feeding guidelines and subsequent infant weight gain. METHODS Participants were mother-infant dyads from the Infant Feeding Practices Study II (N = 1447). Main study variables were PPD, breastfeeding intensity, addition of cereal to infant formula, and age of introduction to solid foods. RESULTS In logistic models adjusted for sociodemographic factors, mothers with PPD were 1.57 times (95% confidence interval [CI]: 1.16, 2.13) more likely to breastfeed at low intensity and 1.77 times (95% CI: 1.16, 2.68) more likely to add cereal to infant formula. Although PPD was associated with the early introduction to solid foods (odds ratio: 1.42; 95% CI: 1.07, 1.89), this relationship was not significant after adjusting for potential confounders. A small but significantly greater average weight gain at 6 months was observed among infants of mothers with PPD (10.15 lb, SD = 2.32 vs. 9.85 lb, SD = 2.32). DISCUSSION Screening for PPD at well-child visits may lead to improved maternal health outcomes and the prevention of early life risk factors for childhood obesity.

Prepregnancy body mass index, socioeconomic status, race/ethnicity and breastfeeding practices

Abstract Objective: While socioeconomic status (SES) and race/ethnicity are known predictors of breastfeeding practices, the added disparity caused by the rising rates of obesity among women of childbearing age remains untested. The purpose of this study was to examine differences in breastfeeding initiation and duration among black, white and Hispanic women of low and middle SES within the context of prepregnancy body mass index (BMI). Methods: Data from the Early Childhood Longitudinal Study-Birth Cohort were analyzed. Adjusted logistic regression models were built to examine differences in breastfeeding initiation and duration for the three racial/ethnic groups of low and middle SES. Results: Normal BMI Hispanic women of low SES demonstrated higher rates of breastfeeding initiation (74%) compared to other groups. Overweight/obese black women of low SES had lower rates of breastfeeding initiation. Overweight/obese Hispanic women of middle SES were significantly less likely to continue breastfeeding up to 4 months (OR: 0.65, 95% CI: 0.41, 0.98) compared to their white counterparts. Among women who initiated breastfeeding, overweight/obese white women of low SES had the highest rate of stopping within two months of giving birth (66.7%). Conclusions: Examination of SES and racial/ethnic differences within the context of prepregnancy weight revealed specific groups with low rates of breastfeeding initiation and duration. Interventions tailored for these at-risk groups are needed to increase the overall proportion of mothers and infants who benefit from the positive health outcomes associated with breastfeeding.

Life Stressors and Barriers to Timely Prenatal Care for Women with High-Risk Pregnancies Residing in Rural and Nonrural Areas

PURPOSE To identify the contribution of life stressors and barriers to the untimely initiation of prenatal care for women with high-risk pregnancies living in rural and nonrural areas. METHODS Data collected in 10 U.S. states by the 2006-2008 Pregnancy Risk Assessment Monitoring System (PRAMS) were used (n = 34,161). Data were weighted to reflect the PRAMS complex survey design. Separate logistic regression models derived adjusted odds ratios for untimely prenatal care initiation based on several life stressors and barriers. RESULTS Women with high-risk pregnancies living in rural areas were more likely to report late initiation of prenatal care (17.5% vs. 14.6%). The most frequently reported life stressors were the same for both cohorts: Moving, having a very sick family member, arguing more than usual with their partners, and having bills they could not pay. The most frequently cited barriers were also the same for both groups: Not having enough money or insurance for health care visits and not being able to get an appointment when they wanted one. Having two or more barriers increased the risk of late prenatal care initiation by 2.85-fold for rural women and 2.01-fold for nonrural women. CONCLUSION To increase timely prenatal care initiation, preconception interventions are needed that address common life stressors and barriers shared by women living in rural and nonrural areas.

Testing Orem's Theory of Self-Care Deficit: Dependent Care Agent Performance for Children

The purpose of this study was to test Orems theory of self-care deficit, one of three constituent theories included in her general self-care deficit theory of nursing. Specifically, the relationship between dependent care agent performance and basic conditioning factors was examined. Dependent care agent performance for children was defined as health promotion and self-care activities provided by a responsible adult on behalf of the child. The Dependent Care Agent Questionnaire was used with a sample of 380 mothers of children from ages 1 to 16 years. The hypothesis that basic conditioning factors influenced dependent care agent performance was supported (R2 = .13, p = .0001).

Nature and nurture in the development of childhood obesity: early infant feeding practices of overweight/obese mothers differ compared to mothers of normal body mass index

Abstract Objective: The purpose of this study was to describe early infant feeding practices among overweight/obese mothers using the Infant Feeding Practices Study II (IFPS II). Methods: In this study, we used data pertaining to the first 2 months postpartum of IFPS II. The data set includes 2387 mothers who provided information about infant feeding habits at the 2-month postpartum period. Results: Overweight/obese mothers were less likely to breastfeed exclusively at 2 months infant age and more likely to breastfeed at low intensity the first 2 months compared to mothers of normal body mass index (BMI). Logistic regression analysis revealed, that after controlling for potential confounders, obese mothers were 1.38 (95% CI: 1.11, 1.72) times more likely to introduce solids to their infants before 4 months of age, and 1.37 (95% CI: 1.10, 1.89) times more likely to add cereal to the infant formula than their normal BMI counterparts. Conclusions: In conclusion, overweight/obese mothers not only fall short of clinical practice guidelines in regards to breastfeeding, but also are more likely to initiate early introduction (<4 months infant age) to solid foods compared to their normal BMI counterparts. Interventions should be targeted to this group.

Nursing practice model for maternal role sufficiency

In 1975 Meleis set forth a conceptual framework for nursing practice centered on the concepts of role insufficiency and role supplementation. Later, Millor introduced a parental role sufficiency model for nursing research in child abuse and neglect. Based on the works of Meleis and Millor, a nursing practice model is proposed that focuses on maternal role sufficiency. It includes assessment of prenatal characteristics, measurement of developmental and health-illness outcomes, and preventive role supplementation intervention.

Identifying high-risk subgroups for alcohol consumption among younger and older pregnant women.

Abstract Aims: Recent studies indicate that older women are more likely to consume alcohol during pregnancy, but subgroups at highest risk within the context of maternal age have not been identified. This study identifies subgroups at risk for alcohol use during pregnancy among three age categories using classification and regression trees (CART) analysis. Methods: Using the 2002–2009 Pregnancy Risk Assessment Monitoring System (PRAMS) dataset (311,428 records of U.S. women), logistic regression and classification trees were constructed separately for age groups, ≤24, 25–29, and ≥30 years. Results: Overall, 6.5% of women reported drinking alcohol during the last trimester of pregnancy. Alcohol consumption by age group was: 3.7% for ≤24, 5.7% for 25–29, and 10.1% for ≥30 years of age. Women ≤24 years were at greater risk of consuming alcohol if they also smoked (5.8%). Among nonsmokers, higher levels of education and being Hispanic were associated with a 35% increase in alcohol use. Distinct high-risk subgroups emerged for the 25–29-year-old group. Specifically, 12.8% of non-obese women who reported having experienced abuse during pregnancy also reported drinking alcohol in the last trimester. About 16% of women ≥30 years with at least 16 years of education, White or Hispanic with normal or underweight BMI, drank alcohol during their last trimester. Conclusions: Given limited health care resources for prevention and treatment, the early identification of high-risk groups for prenatal alcohol use is critical. This study provides evidence that risk factors contributing to alcohol consumption during pregnancy may differ by maternal age.

Maternal–Child Nutrition Practices and Pediatric Overweight/Obesity in the United States and Chile: A Comparative Study

Childhood overweight/obesity is now epidemic in both developed countries and those undergoing economic transition. This study compared maternal and school-age child nutrition practices and body mass index in the United States and in Chile. Children (125 in the United States, 121 in Chile) and their mothers (116 in the United States, 101 in Chile) participated. Findings indicated that child nutrition practices were comparable, but mothers in the U.S. group demonstrated fewer healthy nutrition practices on behalf of their children. Significant associations were found between maternal and child nutrition practices. Substantially more children in the U.S. sample were overweight/obese. Implications for practice are presented.
