Many studies have reported a positive association between BMI and socioeconomic status (SES).

Objective To examine the association between BMI and wealth index in an urban slum setting in Nairobi, Kenya. Methods A total of 2003 adults between 40 and 60 years of age were included. BMI was derived from direct weight and height measurements. Wealth Index was computed using the standard principal component analysis of household amenities ownership. The relationship between BMI and wealth index was assessed using both linear and logistic regression models. Results We found that BMI linearly increased across the five quintiles of wealth index in both men and women, after adjusting for potential confounding factors. The prevalence of obesity increased from 10% in the first wealth quintile to 26.2% in the fifth wealth quintile. The average BMI for women entered the overweight category at the second quintile wealth status, or the third quintile for the total population. Conclusion There exists a strong positive relationship between BMI and wealth index in slum settings. Health promotion interventions aimed at reducing obesity may consider using wealth index in priority setting.","PeriodicalId":44052,"journal":{"name":"Global Health Epidemiology and Genomics","volume":"3 ","pages":"e11"},"PeriodicalIF":1.9,"publicationDate":"2018-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1017/gheg.2018.10","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36531497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronic obstructive pulmonary disease (COPD) is a major public health problem. COPD is the end result of a susceptible lung being exposed to sufficient environmental stimulus. Caused principally by tobacco smoking and household air pollution (HAP), COPD is a silent killer in lowand middle-income countries (LMICs): an estimated 328 million people have COPD worldwide [2], and in 15 years, COPD is expected to become the leading cause of death [3]. The relentless decline in lung function that characterises COPD is associated with progressive symptoms and functional impairment, with susceptibility to respiratory infections called ‘exacerbations’. Exacerbations are responsible for much of the morbidity and mortality. COPD has a significant impact on quality of life for those living with the condition, and on local economies for those affected, those caring for the affected and health services. A population literally struggling for breath is, in consequence, unproductive. The majority of cases of chronic lung disease are preventable. Exposure reduction initiatives must focus on tobacco control, and cook-stove interventions: either cleaner fuel (ideally), or better ventilation (at the least). Awareness campaigns and health programmes have the potential to revolutionise the diagnosis and management of COPD and COPD exacerbations, improving quality of life and health service cost and burden. LMICs face unique challenges in managing COPD, including sub-optimal and diverse primary care systems which present challenges with diagnosis and management, especially during exacerbations. A better understanding of how to prevent, diagnose and manage COPD in both rural and urban settings would make a real difference in countries of need. Two important aspects to consider when addressing the global economic burden of COPD are that of underdiagnosis and comorbidities [4]. Firstly, COPD remains underdiagnosed in many jurisdictions [5]. Studies included in reviews focusing on the global economic burden of COPD are all based on diagnosed COPD, and a simple multiplication of these values by the number of COPD patients to calculate the overall economic burden of COPD will underestimate the contribution of undiagnosed COPD [5]. Secondly, COPD is known to be associated with a significant number of comorbid conditions, and estimating costs that are directly attributable to COPD fails to consider the burden of such comorbidities [4]. Adjusting for comorbidities by calculating excess costs with an appropriate comparison group can provide a better opportunity, but even this results in an underestimation of the costs of the comorbidities [6–8].","PeriodicalId":44052,"journal":{"name":"Global Health Epidemiology and Genomics","volume":"3 ","pages":"e4"},"PeriodicalIF":1.9,"publicationDate":"2018-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1017/gheg.2018.1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36193135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
