Population attributable risk of key modifiable risk factors associated with non-exclusive breastfeeding in Nigeria

AbstractObjective:To identify modifiable risk factors associated with early initiation of breastfeeding (EIBF) and exclusive breastfeeding (EBF) in Colombia.Design:Cross-sectional study from the 2010 Colombia nationally representative Demographic Health Survey (DHS). Studied exposures were categorized into five hierarchical blocks of increasing proximity to the outcomes: household, maternal, health systems, child, and early feeding characteristics. The two outcomes examined were delayed breastfeeding initiation among infants <24 months and interruption of EBF among infants <6 months. Prevalence ratios were computed using Poisson regression analysis with robust error variance, adjusted for sampling weights, following a hierarchical modelling approach.Setting:Nationally representative cross-sectional survey from Colombia.Participants:The EIBF analytical sample included 6592 and the EBF sample 1512 women with young children.Results:EIBF prevalence was 65·6 % in children under 24 months and EBF was 43 % in infants under 6 months. Modifiable risk factors associated with delayed breastfeeding initiation were: C-section (PR = 2·08, CI 95 % = 1·92, 2·25), maternal overweight/obesity (PR = 1·09, CI 95 % = 1·01, 1·17), lack of skilled attendant at birth (PR = 1·09, CI 95 % = 1·01, 1·18). Modifiable risk factors for EBF interruption were C-section (PR = 1·12, CI 95 % = 1·02, 1·23) and prelacteal feeding (PR = 1·51, CI 95 % = 1·37, 1·68). Non-pregnancy intention was a protective factor for EBF interruption (PR = 0·82, CI 95 % = 0·72, 0·93).Conclusions:C-section, lack of skilled attendant at birth, prelacteal feeding, maternal nutritional status, and pregnancy intention were modifiable factors associated with suboptimal breastfeeding practices in Colombia.

Modifiable Risk Factors

Introduction: The prevalence of hyperuricemia is increasing world widely; the understanding of population attributable faction of modifiable risk factors is important for disease prevention. Given the sparse evidence on how modifiable risk factors influence hyperuricemia in mainland China, we aim to explore the effect of excess weight and alcohol consumption and the population attributable fractions of hyperuricemia based on a national survey in mainland China. Methods: Using data from China National Health Survey which included 31746 Han Chinese aged 20-80 from ten provinces, we estimated the prevalence and modifiable risk factors (overweight/obesity and alcohol consumption)of hyperuricemia. Hyperuricemia was defined as serum uric acid > 417 μmol/L in men and > 340 μmol/L in women. Restricted cubic spline models were used to demonstrate the linear and non-linear association between exposures and hyperuricemia. The adjusted population attributable risk (PAR) was calculated to understand the relative importance of each modifiable risk factor. Results: The prevalence of hyperuricemia was 25.1% in men and 15.9% in women. The population fraction of hyperuricemia cases that could be avoided by weight loss was 20.6% (19.2% to 22.0%) in men and 18.1% (17.1% to 19.0%) in women. The PAR of alcohol consumption was 12.8% (8.5% to 17.1%) in men. Participants from southwest China had the highest hyperuricemia prevalence (47.9% in men and 29.9% in women), but with lower PAR of modifiable risk factors, especially in men (16.7%). Subjects in North China had lower hyperuricemia prevalence but higher PAR of modifiable risk factors. 44.8% male hyperuricemia cases in Inner Mongolia (26.9% of hyperuricemia prevalence) and 37.7% cases in men from Heilongjiang (34.4% of hyperuricemia prevalence) were attributable to overweight/obesity and alcohol consumption. Conclusion: There are significant sex and geographic difference on population attributable risk of hyperuricemia due to modifiable risk factors. More tailored prevention strategies are needed to prevent hyperuricemia through weight loss and the reduction of alcohol consumption.

The Impact

Background: Up to 53.7% of all cases of dementia are assumed to be due to Alzheimer disease (AD), while 15.8% are considered to be due to vascular dementia (VaD). In Europe, about 3 million cases of AD could be due to 7 potentially modifiable risk factors: diabetes, midlife hypertension and/or obesity, physical inactivity, depression, smoking, and low educational level. Aims: To estimate the number of VaD cases in Europe and the number of AD and VaD cases in Italy attributable to these 7 potentially modifiable risk factors. Methods: Assuming the nonindependence of the 7 risk factors, the adjusted combined population attributable risk (PAR) was estimated for AD and VaD. Results: In Europe, adjusted combined PAR was 31.4% for AD and 37.8% for VaD. The total number of attributable cases was 3,033,000 for AD and 873,000 for VaD. In Italy, assuming a 20% reduction of the prevalence of each risk factor, adjusted combined PAR decreased from 45.2 to 38.9% for AD and from 53.1 to 46.6% for VaD, implying a 6.4 and 6.5% reduction in the prevalence of AD and VaD, respectively. Conclusion: A relevant reduction of AD and VaD cases in Europe and Italy could be obtained through primary prevention.
