Background: In recent years, there has been a growing understanding that organizational culture is related to an organization's performance. However, few studies have examined organizational culture in medical group practices. Objectives: The purpose of this study was to examine the relationship of organizational culture on provider job satisfaction and perceived clinical effectiveness in primary care pediatric practices. Research Design: This cross-sectional study included 36 primary care pediatric practices located in Connecticut. Participants: There were 374 participants in this study, which included 127 clinicians and 247 nonclinicians. Measures: Office managers completed a questionnaire that recorded staff and practice characteristics; all participants completed the Organizational Culture Scale, a questionnaire that assessed the practice on four cultural domains (i.e., group, developmental, rational, and hierarchical), and the Primary Care Organizational Questionnaire that evaluated perceived effectiveness and job satisfaction. Results: Hierarchical linear models using a restricted maximum likelihood estimation method were used to evaluate whether the practice culture types predicted job satisfaction and perceived effectiveness. Group culture was positively associated with both satisfaction and perceived effectiveness. In contrast, hierarchical and rational culture were negatively associated with both job satisfaction and perceived effectiveness. These relationships were true for clinicians, nonclinicians, and the practice as a whole. Conclusions: Our study demonstrates that practice culture is associated with job satisfaction and perceived clinical effectiveness and that a group culture was associated with high job satisfaction and perceived effectiveness.

To examine the relation between mouse allergen exposure and asthma in Puerto Rican children. Mus m 1, Der p 1, Bla g 2, and Fel d 1 allergens were measured in dust samples from homes of Puerto Rican children with (cases) and without (controls) asthma in Hartford, CT (n = 449) and San Juan (SJ), Puerto Rico (n = 678). Linear or logistic regression was used for the multivariate analysis of mouse allergen (Mus m 1) and lung function (FEV₁ and FEV₁/FVC) and allergy (total IgE and skin test reactivity (STR) to ≥1 allergen) measures. Homes in SJ had lower mouse allergen levels than those in Hartford. In multivariate analyses, mouse allergen was associated with higher FEV₁ in cases in Hartford (+70.6 ml, 95% confidence interval (CI) = 8.6–132.7 ml, P = 0.03) and SJ (+45.1 ml, 95% CI = −0.5 to 90.6 ml, P = 0.05). In multivariate analyses of controls, mouse allergen was inversely associated with STR to ≥1 allergen in non-sensitized children (odds ratio [OR] for each log-unit increment in Mus m 1 = 0.7, 95% CI = 0.5–0.9, P<0.01). In a multivariate analysis including all children at both study sites, each log-increment in mouse allergen was positively associated with FEV₁ (+28.3 ml, 95% CI = 1.4–55.2 ml, P = 0.04) and inversely associated with STR to ≥1 allergen (OR for each log-unit increment in Mus m 1 = 0.8, 95% CI = 0.6–0.9, P<0.01). Mouse allergen is associated with a higher FEV₁ and lower odds of STR to ≥1 allergen in Puerto Rican children. This may be explained by the allergen itself or correlated microbial exposures.

Parents influence adolescents’ weight status through different strategies used in the home environment, including parenting styles (PSs), food parenting practices (FPPs), and family meal frequency. As the prevalence of obesity is higher among African American adolescents, investigation of which parental strategies serve as an adjustable factor for the prevention of obesity is critical. First, this study aims to examine the relationship between the different parenting influences and obesity statuses of both parents and 10–17-year-old adolescents among African American families. Second, it aims to examine the correlation between PSs and FPPs and frequency of family meals. A total of 211 parent–adolescent dyads completed an online survey using Qualtrics. Four PSs (i.e., authoritative, authoritarian, setting rules/expectations, and neglecting) and four FPPs (i.e., monitoring, reasoning, copying, and modeling) were identified for this study, along with family meal frequency. Body mass index (BMI) percentile and BMI were used to assess the obesity status of the adolescents and parents, respectively. No correlation was found between the adolescents’ and parents’ obesity status and the PSs and FPPs, while the adolescents’ BMI percentile was significantly correlated with parental BMI. However, a higher number of family meals decreased the likelihood of obesity among the adolescents to some extend and depended on the type of BMI used. An authoritative PS was the only style related to family meal frequency, while three FPPs, namely, monitoring, reasoning, and modeling, were related to a greater number of family meals in African American families. The findings of this study can be used in the development of parental education workshops/sessions, with consideration of the cultural differences in African American families, and can help parents to adopt the best parenting strategy to promote the healthy weight status of their adolescents.

Summary: Rationale: Little is known about breastfeeding and asthma in Puerto Ricans, the ethnic group most affected by this disease in the US. We examined the relation between the currently recommended duration of breastfeeding and asthma in school‐aged Puerto Rican children.Methods: Case‐control study of 1,127 Puerto Rican children aged 6–14 years living in Hartford, Connecticut (n = 449) and San Juan, Puerto Rico (n = 678). Parental recall of breastfeeding was categorized based on duration and according to current guidelines (i.e., none, 0–6 months, and >6 months). Asthma was defined as parental report of physician‐diagnosed asthma and wheeze in the previous year. We used logistic regression for the multivariate analysis, which was conducted separately for each study site and for the combined cohort. All multivariate models were adjusted for age, gender, household income, atopy, maternal asthma, body mass index, early‐life exposure to environmental tobacco smoke, and (for the combined cohort) study site.Results: After adjustment for covariates, children who were breastfed for up to 6 months had 30% lower odds of asthma (95% CI = 0.5–1.0, P = 0.04) than those who were not breastfed. In this analysis, breastfeeding for longer than 6 months was not significantly associated with asthma (OR = 1.5, 95% CI = 1.0–2.4, P = 0.06).Conclusions: Our results suggest that breastfeeding for up to 6 months (as assessed by parental recall) is associated with decreased odds of asthma in Puerto Rican children, and that there is no additional beneficial effect of breastfeeding for over 6 months. These results support current recommendations on the duration of breastfeeding in an ethnic group at risk for asthma. Pediatr Pulmonol. 2015; 50:527–534.
