Exercise participation and self-rated health: Do common genes explain the association?

The purpose of this study is to investigate whether there is an association between exercise participation and self-rated health and whether this association can be explained by common genes and/or common environmental influences. In a sample of 5,140 Dutch adult twins and their non-twin siblings from 2,831 families, exercise participation (sedentaries, light or moderate, vigorous exercisers) and self-rated health were assessed by survey. To investigate the etiology of the association, bivariate genetic models using structural equation modeling were applied to the data. The correlation between exercise participation and self-rated health is significant but modest (r = 0.20). Exercise participation and self-rated health are both heritable (around 50% of the variance of both phenotypes is explained by genetic factors). The genetic factors influencing exercise participation and self-rated health partially overlap (r = 0.36) and this overlap fully explains their phenotypic correlation. We conclude that the association between exercise and self-rated health can be explained by genes predisposing to both exercise participation and self-rated health. These genes may directly influence both phenotypes (pleiotropy). Alternatively, genes that affect exercise or self-rated health may indirectly influence the other phenotype through a causal relationship. We propose that identification of the genes that cause differences in␣exercise behavior will help resolve the issue of causality.     

Cultural values: can they explain self-reported health?

Purpose

Self-reported health (SRH) is a measure widely used in health research and population studies. Differences in SRH have been observed between countries and cultural values have been hypothesized to partly explain such differences. Cultural values can be operationalized by two cultural dimensions using the World Values Survey (WVS), namely the traditional/rational–secular and the survival/self-expression dimension. We investigate whether there is an association between the WVS cultural dimensions and SRH, both within and between countries.

Methods

Data from 51 countries in the WVS is used and combined with macroeconomic data from the Worldbank database. The association between SRH and the WVS cultural dimensions is tested within each of the 51 countries and multilevel mixed models are used to test differences between these countries. Socio-demographic and macroeconomic variables are used to correct for non-cultural variables related to SRH.

Results

Within countries, the survival/self-expression dimension was positively associated with SRH, while in most countries there was a negative association for the traditional/rational–secular dimension. Values range between 4 and 17% within countries. Further analyses show that the associations within countries and between countries are similar. Controlling for macroeconomic and socio-demographic factors did not change our results.

Discussion

The WVS cultural dimensions predict SRH within and between countries. Contrary to our expectations, traditional/rational–secular values were negatively associated with SRH. As SRH is associated with cultural values between countries, cultural values could be considered when interpreting SRH between countries.

     

WA health practitioners and cooking: How well do they mix?

Aim: The aim of the present study was to assess the views and experiences of WA practitioners on the use of cooking as a public health nutrition intervention. Methods: A 39‐point online questionnaire was constructed using Survey Monkey. The questionnaire was distributed via email distribution lists targeting practitioners working in public health nutrition. Questions were focused around four objectives relating to: the value of cooking skills in public health, practitioner cooking skills and training, practitioner views on cooking as a health intervention and practitioner experiences in conducting cooking demonstrations. Results: A total of 84 practitioners completed the questionnaire, of which over half (58%) were employed in dietetic specific positions at the time of the survey. There was overwhelming agreement that cooking skills are an important factor in the prevention of nutrition‐related disease, and that cooking skill interventions have the potential to change dietary intakes. However, only one quarter of practitioners indicated that cooking skill interventions were a significant part of their current role. Over half (58%) of the practitioners surveyed had either conducted or assisted in a cooking demonstration or cooking class in the last 12 months. Conclusions: WA practitioners place a high value on the use of cooking as a public health nutrition intervention. Practitioners felt they have good knowledge and skills in cooking but indicated the need to know more about conducting cooking skill interventions. The findings suggest the need to improve outcome evaluation as a component of cooking skill interventions to assess long‐term behaviour change.     

Mothers' attitudes and concerns about their children smoking: do they influence kids?

BACKGROUND: The effects of mothers' attitudes and concerns about tobacco use on whether their children take up smoking are largely unknown. This study examined the predictive effects of mothers' attitudes about tobacco and concerns about their children smoking. METHODS: Self-reported data from a large number of 12th-grade students (2,736) and their mothers were used. Mothers' attitudes and concerns were assessed when their children were 3rd graders (age 8), at the start of the smoking acquisition period; their children were then followed prospectively (with attrition of only 5%) for 9 years to the end of the period (12th grade) for the assessment of smoking behavior. RESULTS: In households in which both parents are nonsmokers, strong maternal antismoking attitudes are associated with a statistically significant approximately 50% reduction (P < 0.05) in the prevalence of smoking by adolescent children. In contrast, in households in which one or both parents are current smokers, there was no reduction in adolescent smoking associated with mothers' antismoking attitudes. CONCLUSIONS: Maternal antismoking attitudes when their children are young predict adolescents' adoption of smoking at 12th grade, but only when parental behavior is consistent with these attitudes.     

Systematic health, environment and safety activities: do they influence occupational environment, behaviour and health?

This study investigated the relationships between systematic health, environment and safety (HES) activities (as defined by Norway's Internal Control Regulation), the working environment, and workers' health-related behaviour and health. A questionnaire on systematic HES activities was answered by 237 managers of motor vehicle repair garages. A further questionnaire, on the working environment, health-related behaviour and health, was answered by workers (n = 2174) from the same garages. Using regression analysis, systematic HES activities were positively and significantly correlated with the following separate outcome variables, measured at an individual level: satisfaction with HES activities, physical working environment, social support, HES-related management support, health-related support, and control and workers' participation in activities related to occupational health. Workers at garages with systematic HES activities reported fewer musculoskeletal symptoms. Firm conclusions on the direction of causality are difficult to draw because of the cross-sectional design.     

Thin adolescents: Who are they? What do they do? Socio-demographic and use-of-time characteristics

ObjectivesExamine: (1) the anthropometric, socio-demographic and use-of-time characteristics of thin adolescents, and (2) compare these characteristics to other weight status categories.MethodsData were from the 2007 National Children's Nutrition and Physical Activity Survey which collected data on a random sample of 2200 9 to 16 year old Australians from February to August 2007. Seven socio-demographic variables, anthropometric data (height and weight were measured) and nine use-of-time variables were used, and compared across the weight status categories. Physical activity was measured using pedometers and the Multimedia Activity Recall for Children and Adults.Results5.3% of adolescents were classified as thin, a percentage which did not significantly vary by age, sex, indigenous status, household income, education level or family structure. Relative to other adolescents, thin adolescents were shorter and lighter. Thin adolescents were less active than their normal weight peers, but walked further and accumulated significantly less screen and TV time than obese adolescents.ConclusionThin adolescents were found in similar proportions across all socio-demographic bands. Thin adolescents recorded similar physical activity levels to their normal weight peers, but were more active than obese adolescents. The findings from the study support in part the theory of thinness related developmental delay.     

Adolescent clients of primary health care services. How do they live? Why do they seek help, and how do they express themselves?

The objective of this study was to characterize adolescent clients of community-based primary health care services in order to understand: 1) how they express themselves when they seek medical help; 2) the health care they receive; and 3) key social and family factors. Among 35 urban primary care services belonging to the municipal public health department in Pelotas, Rio Grande do Sul State, Brazil, 10 were randomly selected, and all individuals between 13 and 19 years of age who had previously had an appointment with a non-psychiatric physician were interviewed during a three-month period (n = 463). Use of the services has more of a more curative than preventive focus. Males seek medical help less frequently and mainly due to physical complaints. Females tend to express themselves on the basis of sexual problems. Few adolescents expressed their emotional problems, although some mentioned family and school problems as well as stressful situations.     

Do Latino immigrants link self-rated health with BMI and health behaviors?

OBJECTIVES: To assess the association between self-rated health, obesity, and self-reported health behaviors of Latino immigrants METHODS: Two hundred two Latino immigrants (mean age=31.63, SD=8.30, 54% female) participated in a 15-minute interview and height and weight measurements. RESULTS: Participants reporting good to excellent health reported engaging in physical activity during the past month (P<.05), eating more fruits and vegetables (P<.001 and P<.01 respectively), and watching less television (P<.01) than did those who reported fair to poor health. Self-rated health was not associated with BMI. CONCLUSIONS: Greater attention to Latinos' self-perception of health in relation to weight is needed to develop interventions to improve health status.     

Whiners and deniers – What does self-rated health measure?

Self-rated health is a widely used measure of health typically obtained from a question, “How do you rate your health?” Despite the measure’s popularity, debates continue as to what exactly self-rated health captures. This study augments the rich literature on the construct of self-rated health using a unique measurement approach. We conceptualize self-rated health as consisting of two components: latent health and reporting behaviour. We operationalize a preference-standardized health-related quality of life as a measure of latent health, and its systematic deviation from self-rated health as a measure of reporting behaviour. Using the 2005 Canadian Community Health Survey, we assess comparatively how the deviations between self-rated health and latent health, measured by the Health Utilities Index Mark 3, vary systematically by demographic, socioeconomic, and cultural factors. We present reporting behaviour by these factors in terms of pessimism and optimism relative to the assessment of the average Canadian. Our analysis shows reporting behaviour statistically and clinically significantly varies by age and socioeconomic status: those aged 80+ years and those with less income and education exhibit optimism about their health. In addition, our analysis indicates a tendency for persons with healthier lifestyles to be slightly pessimistic about their health. Our results imply that it may be misleading to take self-rated health at face value as a measure of health status for applications where preferences should be standardized. For this popular measure to continue to play an important role in population health research and policy development, its users must acknowledge and understand the determinants of self-rated health, including reporting behaviour.     

Alcohol and health: do we know enough?

This North East of England survey aimed to evaluate the level of knowledge about alcohol of groups, which included doctors, nurses and the police, who have a role to play in promoting health education. A comparison was made with sectors of the general public, known to be at risk from alcohol-related diseases, particularly young people and those in middle management in industry and commerce. The survey found that a proportion of doctors are unaware of the safe limits of alcohol consumption, and more than a third of the nurses were unaware that these limits were lower for women. Although campaigns did not appear to be reaching middle aged, and other at-risk groups 16-18-year-olds were well informed.     

Ethnic differences in self-rated and functional health: does immigrant status matter?

The current study examines self-rated health status and functional health differences between first-generation immigrant and Canadian-born (CB) persons who share the same ethnocultural origin, and the extent to which such differences reflect social structural and health-related behavioural contexts. Multivariate analyses of data from the 2000/2001 Canadian Community Health Survey indicate that first-generation immigrants of Black and French ethnicity tend to have better health than their CB counterparts, while the opposite is true for those of South Asian and Chinese origins, providing evidence that for these groups, immigrant status matters. West Asians and Arabs and other Asian groups are advantaged in health regardless of country of birth. Health differences between ethnic foreign-born and CB persons generally converge after controlling for sociodemographic, socioeconomic status (SES), and lifestyle factors. Analysis of the data does however reveal extensive ethnocultural disparities in self-rated and functional health within both the immigrant and CB populations. Implications for health care policy and programme development are discussed.     

Medicare beneficiary counseling programs: what are they and do they work?

Medicare beneficiaries face myriad rules, conditions, and exceptions under the Medicare program. As a result, State Information, Counseling, and Assistance (ICA) programs were established or enhanced with Federal funding as part of the Omnibus Budget Reconciliation Act (OBRA) of 1990. ICA programs utilize a volunteer-based and locally-sponsored support system to deliver free and unbiased counseling on the Medicare program and related health insurance issues. This article discusses the effectiveness of the ICA model. Because the ICA programs serve as a vital link between HCFA and its beneficiaries, information about the programs' success may be useful to HCFA and other policymakers during this era of consumer information.
