Critical factors for active transportation to school among low-income and minority students. Evidence from the 2001 National Household Travel Survey

BACKGROUND: Walking to school may be an important source of daily physical activity in children's lives, and government agencies are supporting programs to encourage walking to school (e.g., Safe Routes to School and the CDC's KidsWalk programs). However, little research has looked at differences in behavior across racial/ethnic and income groups. METHODS: This cross-sectional study used data from the 2001 National Household Travel Survey to document rates of walking and biking to school among low-income and minority youth in the U.S. (N=14,553). Binary models of the decision to use active transport to school were developed to simultaneously adjust for trip, individual, household, and neighborhood correlates. All analyses were conducted in 2007. RESULTS: The data showed that low-income and minority groups, particularly blacks and Hispanics, use active travel modes to get to school at much higher rates than whites or higher-income students. However, racial variation in travel patterns is removed by controlling for household income, vehicle access, distance between home and school, and residential density. CONCLUSIONS: Active transportation to school may be an important strategy to increase and maintain physical activity levels for low-income and minority youth. Current policy interventions such as Safe Routes to School have the opportunity to provide benefits for low-income and minority students who are the most likely to walk to school.     

The effect of race and residence on the receipt of childhood immunizations: 1993-2001

OBJECTIVE: To determine if rural minority children ages 3-71 months are more likely than similar aged urban minorities to have delays in their immunization status. METHODS: Secondary analysis of the National Health Interview Survey (NHIS) for the years 1993-2001. FINDINGS: There were no substantial differences between the up-to-date immunization status of children living in metropolitan areas compared to children living in rural areas. There does appear to be a delay in introducing new vaccines into rural areas compared to metropolitan areas during the first 2 years of the vaccine recommendation. There were no significant differences in immunization status between Whites, Blacks and Hispanics living in metropolitan and rural areas. CONCLUSIONS: Rural minority children are no more likely than other children to have delayed immunizations.     

The multi-dimensional neighbourhood and health: a cross-sectional analysis of the Scottish Household Survey, 2001

Neighbourhoods may influence the health of individual residents in different ways: via the social and physical environment, as well as through facilities and services. Not all factors may be equally important for all population subgroups. A cross-sectional analysis of the Scottish Household Survey 2001 examined a range of neighbourhood factors for links with three health outcomes and two health-related behaviours. The results support the hypothesis that the neighbourhood has a multi-dimensional impact on health. There was also some evidence that the relationship between neighbourhood factors and health varied according to the population subgroup, although not in a consistent manner.

Health care utilization,cost burden and coping strategies by disability status: an analysis of the Viet Nam National Health Survey

There is a need for nationally representative information on the affordability of health care by disability status to assist in the design of equitable health systems in developing countries. Using the Viet Nam National Health Survey (2001–2002), this paper analyses health care utilization, cost burden and coping strategies for people with disabilities versus the population at large. The results clearly show that the disabled population are more prone to hospitalization, and spend more on inpatient stays and pharmaceuticals. Households with disabled members are at greater risk of catastrophic health expenditures and debt financing, posing a serious threat to economic welfare.

Television viewing and its association with overweight in Colombian children: results from the 2005 National Nutrition Survey: A cross sectional study

Background  

There has been an ongoing discussion about the relationship between time spent watching television and childhood obesity. This debate has special relevance in the Latin American region were the globalization process has increased the availability of screen-based entertainment at home. The aim of this study is to examine the association between television viewing and weight status in Colombian children.     

The role of reported primary race on health measures for multiple race respondents in the National Health Interview Survey

OBJECTIVES: As data for multiple race groups have only recently been collected and tabulated, the current understanding of the health of multiple race groups is not well developed. In the National Health Interview Survey (NHIS), survey respondents who report more than one race are asked to identify a primary race. This report compares selected health and demographic measures by the response to the primary race question and compares estimates for specific primary race groups to corresponding estimates for single race groups. METHODS: Using 1997-2003 NHIS data, several demographic and health measures were compared by reported primary race within the four largest multiple race groups. Then estimates by primary race for these four multiple race groups were compared to those for their single race counterparts. RESULTS: There were few statistically significant associations between reported primary race and health or demographic variables within the four multiple race groups. This lack of association may be due to the small number of multiple race respondents (which results in large standard errors) rather than similarity of point estimates among the subgroups. A greater number of differences between estimates for single race groups and for multiple race respondents who reported the same single race as their primary race were identified. CONCLUSIONS: The apparent lack of association between primary race within a multiple race group and health outcomes suggests that tabulating multiple race responses by primary race is unnecessary for valid health estimates for multiple race groups, at least with available statistical power. However, differences between single race and primary race estimates within a multiple race group suggest that inferences for multiple race respondents using single race estimates may be imprecise for some outcomes.     

Secondary anthropometric data analysis of the National Food Consumption Survey in South Africa: the double burden

OBJECTIVE: There is an increase in the prevalence of overweight and obesity in children worldwide, including South Africa. We investigated the prevalences of overweight, obesity, and stunting in a current generation of children (ages 12 to 108 mo), which has a high prevalence of stunting, and evaluated the determinants of both nutritional disorders. METHODS: Secondary data analysis of the weight and height measurements of 12- to 108-mo-old children (weighted n = 2200, non-weighted n = 2894) during the 1999 National Food Consumption Survey in South Africa is reported. The body mass index reference percentiles recommended for use in children by the International Obesity Task Force were used to determine the prevalence of overweight and obesity, and the National Center for Health Statistics (NCHS) percentiles were used to determine the prevalence of stunting. RESULTS: Nationally, the prevalence of stunting (height-for-age < or = -2 standard deviations, NCHS 50th percentile) in these children was 19.3% (95% confidence interval [CI] = 17.49 to 21.16) and was highest in 1- to 3-y-old children (24.4%) and in children of farm workers on commercial farms (25.6%). The prevalence of combined overweight and obesity (body mass index > or = 25 kg/m(2) in 17.1%, 95% CI = 15.00 to 19.23) at the national level was nearly as high as that for stunting. Further, the types of determinants for stunting and overweight were generally similar (although directionally opposite in degree of risk conferred) and included type of housing, type of toilet in the home, fuel used in cooking, presence of a refrigerator or stove, presence of a television in the house, educational level of the caregiver, and maternal education level. An example of the directionally opposite degree of risk is exemplified by the use of paraffin as a fuel being protective against being overweight (odds ratio = 0.78, 95% CI = 0.63 to 0.97) but predictive of an increased risk for stunting (odds ratio = 1.24, 95% CI = 1.04 to 1.48). Stunting itself conferred an increased risk (odds ratio = 1.80, 95% CI = 1.48 to 2.20) of being overweight. CONCLUSION: Certain defined determinants appear to play important roles in children's nutritional outcomes in relation to stunting and to overweight and obesity.     

Risk factors for overweight and obesity: results from the 2001 National Health Survey

OBJECTIVES: A significant rise in the proportion of overweight and obese adults has produced a serious health epidemic in Australia and worldwide. The current research aimed to identify sociodemographic and behavioural predictors of overweight and obesity among a large representative sample of Australian adults. STUDY DESIGN: We used the National Health Survey conducted by the Australian Bureau of Statistics in 2001. The survey involved a stratified multistage area sample of private dwellings and face-to-face interviews. METHODS: We analysed data from 8643 females and 7600 males who responded to the 2001 National Health Survey. Multinomial logistic regression examined the association of being overweight or obese versus a healthy weight with a range of sociodemographic and behavioural variables. RESULTS: Fewer females than males were overweight while similar proportions were obese. For females and males, overweight and obesity were significantly associated with older age, being born in Australia, not being in a marriage-like relationship, low education, physical inactivity, and being a non/ex-smoker. High household incomes are protective from obesity but not from being overweight. Additionally, females with high levels of area social disadvantage and males in professional or white-collar occupations were more likely to be overweight or obese than a healthy weight. CONCLUSIONS: Reductions in mortality and morbidity associated with overweight and obesity may be achieved by targeting health promotion strategies to high-risk groups such as those who are older, single, Australian born, socioeconomically disadvantaged, physically inactive, and non-smokers.     

Smoking, work status, and gender: analysis of the Brazilian National Household Sample Survey, 2008

This study investigated whether men's and women's work status is associated with current smoking, after adjusting for schooling, income, and health, besides discussing hypotheses for such associations. The sample included individuals 15 to 64 years of age living in metropolitan areas, currently in the work force, and interviewed in the Brazilian National Household Sample Survey (PNAD) in 2008. Prevalence ratios (PR) and 95% confidence intervals (95%CI) were obtained by Poisson regression. After adjusting, smoking prevalence was statistically higher in individuals with informal jobs (men, PR = 1.31, 95%CI: 1.24-1.38; women, PR = 1.22, 95%CI: 1.12-1.31) or who were unemployed (men, PR = 1.31, 95%CI: 1.18-1.44; women, PR = 1.16, 95%CI: 1.03-1.32). Our results confirm that work status is an independent dimension of social inequalities in smoking. The social gradient was steeper in men, but the association between work status and smoking was present in both genders.     

Gender and health in Brazil: considerations based on the National Household Sampling Survey]

As in the principal industrial countries, Brazilian women have lived longer than men. However, paradoxically, women present higher morbidity indicators than men. Knowledge of the Brazilian pattern regarding this matter could be a useful contribution to an understanding of their determinants in our specific reality, as well as enabling us to foresee future trends that would make it possible to plan adjustment in the health system. A morbidity study based on data from the National Household Sample Survey (PNAD/IBGE), was undertaken in ten Brazilian states in 1986 with this in view. Coefficients of the prevalence of perceived morbidity, demand for and utilization of health services according to sex, standardized by age and using the direct method, were built up. As a measurement of the differentials, sex ratios were calculated. The excess of perceived morbidity in women was constant in all the regions. The sex differential in the utilization of health services showed regional variations, suggesting a relationship with the health services supply. Sex differentials were not observed in childhood; the highest values were found during the woman's reproductive period, decreasing sharply after 60 years of age. The pattern is very similar in all regions. In the present study, the findings could be partially explained by the methodology adopted, but they are similar to the findings reported in other countries. The intense transformations in the reproductive pattern and in the social status of Brazilian women probably have a considerable impact on the health status and on the recourse to health services, not as yet evaluated.(ABSTRACT TRUNCATED AT 250 WORDS)     

Alcohol use and wages: new results from the National Household Survey on Drug Abuse

A recent study published in the Journal of Health Economics by French and Zarkin [French, M.T., Zarkin, G.A., 1995. Is moderate alcohol use related to wages? Evidence from four worksites, Journal of Health Economics 14, 319-344] found evidence of a positive, inverse-U-shaped relationship between wages and alcohol consumption for individuals at four worksites. In this paper, we attempted to replicate French and Zarkin's findings using a combined sample of prime-age workers from the 1991 and 1992 National Household Surveys on Drug Abuse (NHSDA). Whereas French and Zarkin found that individuals who consume approximately 1.5 to 2.5 drinks per day have higher wages than non-drinkers and heavy drinkers, we found no evidence of a turning point at this consumption level for either men or women. Our results do suggest that men who use alcohol have approximately 7% higher wages than men who do not drink, and this apparent wage premium is approximately the same over a wide range of alcohol consumption. For women, the estimated alcohol use premium is approximately half as large as for men and is statistically insignificant.     

Health insurance coverage among foreign-born US residents: the impact of race, ethnicity, and length of residence.

OBJECTIVES: This study examined the health insurance status of the US foreign-born population and the influence of race, ethnicity, and length of residence on health insurance status. METHODS: Data were obtained from the 1989 and 1990 National Health Interview Surveys, including the Insurance and Family Resource Supplements. RESULTS: In 1989 and 1990, the foreign-born population was twice as likely as the US-born population to be uninsured (26.2% vs 13.0%). The highest rate of uninsured status, 40.8%, was found among foreign-born Hispanics. Persons who had lived in the United States for less than 15 years were 1.5 to 4.7 times more likely to be uninsured than were US-born Whites. CONCLUSIONS: Foreign-born US residents-especially Hispanics and persons residing in the United States for less than 15 years-are vulnerable to not having health insurance, which may limit their access to medical services. The administrative criteria for public programs may explain the high rates of uninsured status among recent immigrants. Recently enacted federal legislation could substantially increase the number of uninsured among the US foreign-born population, with profound public health implications.     

Model for estimating the population prevalence of chronic obstructive pulmonary disease: cross sectional data from the Health Survey for England

Background  

Chronic obstructive pulmonary disease (COPD) is a major but neglected public health problem. Currently 1.4% of the England population has a clinical diagnosis of COPD, but the true burden of the disease has not been known with certainty, as many cases remain undiagnosed.     

Effects of bioaerosol polluted outdoor air on airways of residents: a cross sectional study

Background: Bioaerosol pollution of workplace and home environments mainly affects airways and mucous membranes. The effect of environmental outdoor residential bioaerosol pollution, for example, livestock holdings, farming, and waste disposal plants, is unclear.

Aims: To investigate the perceived health of residents living in areas with measurable outdoor bioaerosol pollution (for example, spores of Aspergillus fumigatus and actinomycetes), and effects of accompanying odours.

Methods: In a cross sectional study, double blinded to ongoing microbial measurements, doctors collected 356 questionnaires from residents near a large scale composting site, and from unexposed controls in 1997. Self reported prevalence of health complaints during the past year, doctors' diagnoses, as well as residential odour annoyance were assessed. Microbiological pollution was measured simultaneously in residential outdoor air.

Results: Concentrations of >10⁵ colony forming units of thermophilic actinomycetes, moulds, and total bacteria/m³ air were measured 200 m from the site, dropping to near background concentrations within 300 m. Positive adjusted associations were observed for residency within 150–200 m from the site versus unexposed controls for self reported health complaints: "waking up due to coughing", odds ratio (OR) 6.59 (95% confidence interval (CI) 2.57 to 17.73); "coughing on rising or during the day", OR 3.18 (95% CI 1.24 to 8.36); "bronchitis", OR 3.59 (95% CI 1.40 to 9.4); and "excessive tiredness", OR 4.27 (95% CI 1.56 to 12.15). Reports of irritative airway complaints were associated with residency in the highest bioaerosol exposure, 150–200 m (versus residency >400–500 m) from the site, and period of residency more than five years, but not residential odour annoyance. Lifetime prevalence of self reported diseases did not differ with exposure.

Conclusions: Bioaerosol pollution of residential outdoor air can occur in concentrations found in occupational environments. For the first time residents exposed to bioaerosol pollution were shown to report irritative respiratory complaints similar to mucous membrane irritation independently of perceived odours.

     

Sick-listed employees with severe medically unexplained physical symptoms: burden or routine for the occupational health physician? A cross sectional study

Background  

The two primary objectives of this study were to the assess consultation load of occupational health physicians (OHPs), and their difficulties and needs with regard to their sickness certification tasks in sick-listed employees with severe medical unexplained physical symptoms (MUPS). Third objective was to determine which disease-, patient-, doctor- and practice-related factors are associated with the difficulties and needs of the OHPs.
