Abstract
BACKGROUND In epidemiologic studies, association between coffee consumption and esophageal cancer risk is inconsistent. OBJECTIVE The aim of tjis study was to evaluate the effect of coffee on esophageal cancer by combining several similar studies. METHODS We conducted a meta-analysis for association of coffee intake and esophageal cancer incidence. Eleven studies, including 457,010 participants and 2628 incident cases, were identified. A relative risk (RR, for cohort study) or odds ratio (OR, for case-control study) of heavy coffee drinkers was calculated, compared with light coffee drinkers or non-drinkers. The analysis was also stratified by cancer types (esophageal squamous cell carcinoma and esophageal adenocarcinoma), sex, and geographic region. RESULTS The summarized OR of having esophageal cancer in heavy coffee drinkers was 0.93 (95% confidence interval [CI]: 0.73-1.12), compared with light coffee drinkers. When stratified by sex, pathologic type of esophageal cancer, and type of epidemiologic study, we did not find any association of coffee consumption and esophageal cancer incidence. However, an inverse association between coffee consumption and incidence of esophageal cancer was found in East Asia participants with OR of 0.64 (95% CI: 0.44-0.83), but not in Euro-America participants (OR = 1.05; 95% CI: 0.81-1.29). CONCLUSION There is a protective role of coffee consumption against esophageal cancer in East Asians, but not in Euro-Americans.

Measures of Retail Food Store Environments and Sales: Review and Implications for Healthy Eating Initiatives.
Glanz, K, Johnson, L, Yaroch, AL, Phillips, M, Ayala, GX, Davis, EL
Journal of nutrition education and behavior. 2016;(4):280-8.e1
Abstract
OBJECTIVE This review describes available measures of retail food store environments, including data collection methods, characteristics of measures, the dimensions most commonly captured across methods, and their strengths and limitations. METHODS Articles were included if they were published between 1990 and 2015 in an English-language peer-reviewed journal and presented original research findings on the development and/or use of a measure or method to assess retail food store environments. Four sources were used, including literature databases, backward searching of identified articles, published reviews, and measurement registries. RESULTS From 3,013 citations identified, 125 observational studies and 5 studies that used sales records were reviewed in-depth. Most studies were cross-sectional and based in the US. The most common tools used were the US Department of Agriculture's Thrifty Food Plan and the Nutrition Environment Measures Survey for Stores. The most common attribute captured was availability of healthful options, followed by price. Measurement quality indicators were minimal and focused mainly on assessments of reliability. IMPLICATIONS FOR RESEARCH AND PRACTICE Two widely used tools to measure retail food store environments are available and can be refined and adapted. Standardization of measurement across studies and reports of measurement quality (eg, reliability, validity) may better inform practice and policy changes.

Abstract
Cardiovascular disease (CVD) continues to be the leading cause of death and a major source of health disparities in the Unites States and globally. Efforts to reduce CVD risk and eliminate cardiovascular health disparities have increasingly emphasized the importance of the social determinants of health. Neighborhood environments have emerged as a possible target for prevention and policy efforts. Hence there is a need to better understand the role of neighborhood environments in shaping cardiovascular risk. The MESA (Multi-Ethnic Study of Atherosclerosis) Neighborhood Study provided a unique opportunity to build a comprehensive place-based resource for investigations of associations between specific features of neighborhood physical and social environments and cardiovascular risk factors and outcomes. This review summarizes the approaches used to characterize residential neighborhood environments in the MESA cohort, provides an overview of key findings to date, and discusses challenges and opportunities in neighborhood health effects research. Results to date suggest that neighborhood physical and social environments are related to behavioral and biomedical risk factors for CVD and that cardiovascular prevention efforts may benefit from taking neighborhood context into account.

Measuring the food environment and its effects on obesity in the United States: a systematic review of methods and results.
Gamba, RJ, Schuchter, J, Rutt, C, Seto, EY
Journal of community health. 2015;(3):464-75
Abstract
We identified fifty-one peer-reviewed studies that geospatially analyzed the relationship between the community nutrition environment (CNE) and obesity. Eighty percent of studies found at least one significant association between the CNE and obesity. However we calculated the proportion of studies that found at least one significant association between the CNE and obesity in the expected direction for each food store type and measurement technique, and the proportion across the different store types and measurement techniques was just 32%. Different methods for classifying, locating, and analyzing food stores produced mixed results and challenged direct study level comparison.

Communities and community genetics in Ethiopia.
Tadesse, L, Tafesse, F, Hamamy, H
The Pan African medical journal. 2014;:115
Abstract
The rates of congenital and genetic disorders in low and middle income countries are similar or might be higher than in high income countries due to a multitude of risk factors and the dearth of community genetic services. To direct effective preventive, diagnostic and counseling services, collecting data on the incidence and prevalence of various congenital and genetic disorders and their risk factors is a pre-requisite for establishing genetic services at the community level and mainly at the primary health care setting. This brief review is meant to assess the available epidemiological data in Ethiopia pertaining to congenital and genetic disorders on which the future community genetic services could be built. Existing epidemiological data on congenital and genetic disorders in Ethiopia is limited, and the few studies conducted revealed that folate and iodine deficiencies are prevalent among women in the reproductive age. Pregnant women's infection with syphilis and rubella is prevailing. Based on available data, cleft lip and palate, congenital heart diseases, club-foot, and gastro-intestinal malformations are the most common birth defects in Ethiopia. Community based studies to accurately demonstrate the incidence and prevalence levels of these disorders are almost unavailable. To plan for organization and implementation of community genetic services at the primary health care level in Ethiopia, conducting standardized epidemiological studies is currently highly recommended.

A review of risk factors for overweight in preschool children: a policy perspective.
Hawkins, SS, Law, C
International journal of pediatric obesity : IJPO : an official journal of the International Association for the Study of Obesity. 2006;(4):195-209
Abstract
An increasing number of preschool children are becoming overweight. Although many risk factors have been identified for school-age children, less is known about this young age group. Ecological models have been developed to illustrate how individual characteristics, family characteristics, community-level factors, and policies may influence weight gain. We used this model to review factors that influence overweight in children, aged six months to five years, which are amenable to policy intervention in resource-rich countries. We found strong evidence for a direct association between childhood overweight and maternal prepregnancy body size, maternal smoking during pregnancy, and children's television/media use; strong evidence for an inverse relationship between breastfeeding and overweight, and moderate evidence for children's physical activity. There was limited research on community-level factors, policies and interventions. Future policies and interventions should be subject to evaluation and aim to support parents and young children to develop health-related behaviours that may prevent early childhood overweight.
