Impact of Hospitalization for Acute Myocardial Infarction on Adherence to Statins Among Older Adults

Background—Little is known about the impact of hospitalization for an acute myocardial infarction (AMI) on subsequent adherence to statins. Methods and Results—Using administrative claims from a 5% random sample of Medicare beneficiaries, we identified a cohort of Medicare patients aged ≥65 years, hospitalized from 2007 to 2011, taking statins in the year before AMI hospitalization (n=6618). We then determined the proportion of patients nonadherent to statins (proportion of days covered <80%) in the year before AMI hospitalization who became statin adherent (proportion of days covered ≥80%) in the year after AMI hospitalization. The proportion of statin-adherent patients who became nonadherent was also studied. These proportions were compared with patients hospitalized for pneumonia (n=11 471) and patients not hospitalized (n=158 099) in 2010 and 2011. Among patients nonadherent to statins before AMI hospitalization, 37.7% became adherent after discharge. Patients hospitalized for AMI were more likely to become adherent than patients hospitalized for pneumonia (adjusted relative risk: 1.70; 95% confidence interval, 1.57–1.84) or patients not hospitalized (adjusted relative risk: 1.79; 95% confidence interval, 1.68–1.90). Among patients adherent to statins before AMI hospitalization, 32.6% became nonadherent after discharge. Those hospitalized for AMI were less likely to become nonadherent than those hospitalized for pneumonia (adjusted relative risk: 0.93; 95% confidence interval 0.88–0.98) but more likely to become nonadherent than patients without hospitalizations (adjusted relative risk: 1.41; 95% confidence interval, 1.35–1.48). Conclusions—Among nonadherent patients, hospitalization for AMI was associated with increased likelihood of becoming adherent to statins compared with hospitalization for pneumonia or no hospitalizations. Among adherent patients, hospitalization for AMI was associated with increased likelihood of becoming nonadherent to statins compared with no hospitalizations

Social circumstances and cultural beliefs influence maternal nutrition, breastfeeding and child feeding practices in South Africa:

Maternal and child undernutrition remain prevalent in developing countries with 45 and 11% of child deaths linked to poor nutrition and suboptimal breastfeeding, respectively. This also has adverse effects on child growth and development. The study determined maternal dietary diversity, breastfeeding and, infant and young child feeding (IYCF) practices and identified reasons for such behavior in five rural communities in South Africa, in the context of cultural beliefs and social aspects

Does breastfeeding duration decrease child obesity? An instrumental variables analysis

BackgroundMany studies have documented that breastfeeding is associated with a significant reduction in child obesity risk. However, a persistent problem in this literature is that unobservable confounders may drive the correlations between breastfeeding behaviors and child weight outcomes.ObjectiveThis study examines the effect of breastfeeding practices on child weight outcomes at age 2.MethodsThis study relied on population-based data for all births in Oregon in 2009 followed for two years. We used instrumental variables methods to exploit variations in breastfeeding by mothers immediately after delivery and the degree to which hospitals encouraged mothers to breastfeed in order to isolate the effect of breastfeeding practices on child weight outcomes.ResultsWe found that for every extra week that the child was breastfed, the likelihood of the child being obese at age 2 declined by 0.82% [95% CI -1.8% to 0.1%]. Likewise, for every extra week that the child was exclusively breastfed, the likelihood of being obese declined by 0.66% [95% CI -1.4 to 0.06%]. While the magnitudes of effects were modest and marginally significant, the results were robust in a variety of specifications.ConclusionThe results suggest that hospital practices that support breastfeeding may influence childhood weight outcomes
