Community-Level Characteristics Associated With Variations In Rates Of Homelessness Among Families And Single Adults, Jamison D. Fargo, Ellen A. Munley, Thomas H. Byrne, Ann Elizabeth Montgomery, Dennis P. Culhane

Dennis P. Culhane

Objectives. We modeled rates of family and single-adult homelessness in the United States in metropolitan and nonmetropolitan regions and as a function of community-level demographic, behavioral, health, economic, and safety net characteristics.
Methods. We entered community-level characteristics and US Department of Housing and Urban Development point-in-time counts for a single night in January 2009 into separate mixed-effects statistical analyses that modeled homelessness rates for 4 subpopulations: families and single adults inmetropolitan and nonmetropolitan regions.
Results. Community-level factors accounted for 25% to 50% of the variance in homelessness rates across models. In metropolitan regions, alcohol consumption, social support, and several economic …

OBJECTIVE: To perform construct validation of the population-based Dietary Inflammatory Index (DII) using dietary data from two different dietary assessments and serum high-sensitivity C-reactive protein (hs-CRP) as the construct validator.

DESIGN: Using data derived from (i) three 24 h dietary recalls (24HR) at baseline and at the end of each subsequent quarter (i.e. up to fifteen over a year) and (ii) a 7 d dietary recall (7DDR) measured at baseline and then quarterly, regression analyses were conducted to test the effect of the DII score on serum hs-CRP as dichotomous (3 mg/l), while controlling for important potential confounders.

SETTING: Existing …

Health Profile Of Brazilian Mothers In Massachusetts In The Twenty First Century, Carlos Eduardo Siqueira, Teresa Roberts, Fernanda Lucchese Jul 2013

Health Profile Of Brazilian Mothers In Massachusetts In The Twenty First Century, Carlos Eduardo Siqueira, Teresa Roberts, Fernanda Lucchese

C. Eduardo Siqueira

This paper describes the health profile of Brazilian mothers in Massachusetts according to data collected through Massachusetts Standard Certificate of Live Births (1989 revision) filed with the Massachusetts Registry of Vital Records and Statistics during 1999 and 2009. To our knowledge this is the first time that such information is reviewed with a focus on Brazilian immigrants. The findings of this article suggests that Brazilian mothers who gave birth in Massachusetts between 1999 and 2009 fared better than all mothers in Massachusetts in most obstetric health indicators considered.

BACKGROUND: The effectiveness of screening colonoscopy in average-risk adults is uncertain, particularly for right colon cancer. OBJECTIVE: To examine the association between screening colonoscopy and risk for incident late-stage colorectal cancer (CRC). DESIGN: Nested case-control study. SETTING: Four U.S. health plans. PATIENTS: 1039 average-risk adults enrolled for at least 5 years in one of the health plans. Case patients were aged 55 to 85 years on their diagnosis date (reference date) of stage IIB or higher (late-stage) CRC during 2006 to 2008. One or 2 control patients were selected for each case patient, matched on birth year, sex, health plan, …


Estimating The Effect Of A Community-Based Intervention With Two Communities, Mark Van Der Laan, Maya Petersen, Wenjing Zheng May 2013

Estimating The Effect Of A Community-Based Intervention With Two Communities, Mark Van Der Laan, Maya Petersen, Wenjing Zheng

Wenjing Zheng

Due to the need to evaluate the effectiveness of community-based programs in practice, there is substantial interest in methods to estimate the causal effects of community-level treatments or exposures on individual level outcomes. The challenge one is confronted with is that different communities have different environmental factors affecting the individual outcomes, and all individuals in a community share the same environment and intervention. In practice, data are often available from only a small number of communities, making it difficult if not impossible to adjust for these environmental confounders. In this paper we consider an extreme version of this dilemma, in …


Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra May 2013

Why Are There Delays In Seeking Treatment For Childhood Diarrhoea In India?, Nisha Malhotra

Nisha Malhotra

Abstract Aim To examine the barriers and facilitating factors for seeking treatment for childhood diarrhoea and to determine the main causes for delay in seeking treatment.

Methods Data from Indian Demographic and Health survey 2005–06 (NFHS-III) was used. Mothers were asked if their children (<5-years) had suffered from diarrhoea during the two weeks preceding the survey. Data were collected on the time of seeking treatment after start of the illness, and days waited to seek treatment after the diarrhoea started. Multivariate logistic regression analysis was performed to find the determinants of seeking treatment at the health facility and the factors responsible for the “delay” in seeking advice/treatment.

Results Out of a sample of 41,287 children, 3890 (9.4%) reportedly had diarrhoea. Sixty percent of children with diarrhoea were taken to a health facility. Mother's education till higher secondary and above (OR 1.65; 95% CI, 1.08 – 2.54), richest (OR 1.76; 95% CI, 1.24 – 2.48) wealth index, mother's lack of knowledge of oral …
