Associations between the perceived environment and physical activity among adults aged 55-65 years: does urban-rural area of residence matter?

This study aimed to determine whether associations between the perceived environment and physical activity are moderated by urban-rural status among midolder aged adults. Environmental (safety, aesthetics, physical activity environment) and physical activity (total, leisure, transport) data from 3,888 adults (55 to 65 years) from urban and rural areas of Victoria, Australia, were analyzed. Multinomial logistic regression examined interactions between urban-rural status and environments in associations with physical activity. Significant (P < .05) interactions were evident and indicated positive associations only among older rural adults for both safety and aesthetics with total and transport physical activity (e.g., rural adults reporting higher safety were 91% to 118% more likely to have higher activity than rural adults reporting low safety). In contrast, the physical activity environment was positively associated with leisure activity among only urban adults. Findings suggest that some tailoring of physical activity promotion strategies targeting the environment may be required for urban and rural midolder aged adults.

Does the availability of snack foods in supermarkets vary internationally?

BACKGROUND: Cross-country differences in dietary behaviours and obesity rates have been previously reported. Consumption of energy-dense snack foods and soft drinks are implicated as contributing to weight gain, however little is known about how the availability of these items within supermarkets varies internationally. This study assessed variations in the display of snack foods and soft drinks within a sample of supermarkets across eight countries. METHODS: Within-store audits were used to evaluate and compare the availability of potato chips (crisps), chocolate, confectionery and soft drinks. Displays measured included shelf length and the proportion of checkouts and end-of-aisle displays containing these products. Audits were conducted in a convenience sample of 170 supermarkets across eight developed nations (Australia, Canada, Denmark, Netherlands, New Zealand, Sweden, United Kingdom (UK), and United States of America (US)). RESULTS: The mean total aisle length of snack foods (adjusted for store size) was greatest in supermarkets from the UK (56.4 m) and lowest in New Zealand (21.7 m). When assessed by individual item, the greatest aisle length devoted to chips, chocolate and confectionery was found in UK supermarkets while the greatest aisle length dedicated to soft drinks was in Australian supermarkets. Only stores from the Netherlands (41%) had less than 70% of checkouts featuring displays of snack foods or soft drinks. CONCLUSION: Whilst between-country variations were observed, overall results indicate high levels of snack food and soft drinks displays within supermarkets across the eight countries. Exposure to snack foods is largely unavoidable within supermarkets, increasing the likelihood of purchases and particularly those made impulsively.

Associations between fruit and vegetable intake, leisure-time physical activity, sitting time and self-rated health among older adults: cross-sectional data from the WELL study.

BACKGROUND: Lifestyle behaviours, such as healthy diet, physical activity and sedentary behaviour, are key elements of healthy ageing and important modifiable risk factors in the prevention of chronic diseases. Little is known about the relationship between these behaviours in older adults. The purpose of this study was to explore the relationship between fruit and vegetable (F&V) intake, leisure-time physical activity (LTPA) and sitting time (ST), and their association with self-rated health in older adults. METHODS: This cross-sectional study comprised 3,644 older adults (48% men) aged 55-65 years, who participated in the Wellbeing, Eating and Exercise for a Long Life ("WELL") study. Respondents completed a postal survey about their health and their eating and physical activity behaviours in 2010 (38% response rate). Spearman's coefficient (rho) was used to evaluate the relationship between F&V intake, LTPA and ST. Their individual and shared associations with self-rated health were examined using ordinal logistic regression models, stratified by sex and adjusted for confounders (BMI, smoking, long-term illness and socio-demographic characteristics). RESULTS: The correlations between F&V intake, LTPA and ST were low. F&V intake and LTPA were positively associated with self-rated health. Each additional serving of F&V or MET-hour of LTPA were associated with approximately 10% higher likelihood of reporting health as good or better among women and men. The association between ST and self-rated health was not significant in the multivariate analysis. A significant interaction was found (ST*F&V intake). The effect of F&V intake on self-rated health increased with increasing ST in women, whereas the effect decreased with increasing ST in men. CONCLUSIONS: This study contributes to the scarce literature related to lifestyle behaviours and their association with health indicators among older adults. The findings suggest that a modest increase in F&V intake, or LTPA could have a marked effect on the health of older adults. Further research is needed to fully understand the correlates and determinants of lifestyle behaviours, particularly sitting time, in this age group.

Social Capital, Deprivation and Psychological Well-Being among Young Adolescents: A Multilevel Study from England and Wales.

Examining the mechanisms influencing mental health and life satisfaction simultaneously allows for a better understanding of adolescents psychological well-being. Six indicators of neighbourhood social capital (NSC), neighbourhood socioeconomic deprivation (SecD) and their association with psychological well-being among young adolescents aged 10-15 from England and Wales were investigated. Using a random sample of 5201 adolescents (7253 observations) from the UK Household Longitudinal Study merged to aggregated local area census measures, we fitted a series of multilevel models. The findings showed that not being worried about crime and friendship networks mitigated the negative effects of deprivation on adolescent's psychological well-being. These findings suggest that some forms of NSC may have a buffering and protective function, with the strongest effects in deprived neighbourhoods. We further found that psychological well-being of adolescents is dependent on both individual vulnerabilities and neighbourhood context. However caution is required if, and when public health policies are formulated to address this issue, given significant variations (27-36%) in the inter- and intra-individual psychological well-being were found among this group over time. Thus, policies designed to improve psychological well-being among adolescents should take into account the role of social processes in transmitting deprivation's effects, as well as the various forms of social capital.

Arranging appropriate activities immigrant women's ideas of enabling exercise.

OBJECTIVE: Several studies have reported low levels of physical activity among immigrant women. However, few studies have attempted to explore possible causes underlying this phenomenon. This study intended to explore immigrant women's attitudes and experiences of physical activity and exercise. The ultimate goal was to find methods that can increase levels of physical activity among immigrant women. METHODS: A qualitative exploratory study was undertaken in Stockholm County, Sweden, involving 63 immigrant women from Chile, Iraq, and Turkey. Data were collected through interviews in 10 focus groups. The analysis was based on grounded theory approaches. Constant comparative analysis and theoretical sampling were employed to construct categories. MAIN FINDINGS: The model that emerged illustrated the core process, that is, enabling exercise. The model also described the women's attitudes and experiences and their ideas of how exercise can be made possible. The women agreed that the local community should recognize the problem and arrange exercise in familiar places. In addition, they called for activities that felt appropriate. If appropriate exercise was arranged, the women sometimes decided to participate. Otherwise, they hesitated or waited. CONCLUSION: If appropriate activities are arranged, levels of physical activity and exercise might increase among immigrant women. Future studies could explore specific activities that can facilitate immigrant women's opportunities to exercise.

Physical activity, exercise and self-rated health: a population-based study from Sweden.

BACKGROUND: In order to screen for the most inactive individuals in the population and target health-related interventions where they are most needed it is important to assess different forms of physical activity in population-based studies. The aims were (1) to identify the most inactive individuals in the population by assessing two dimensions of physical activity, (2) to investigate the correlation between exercise and total physical activity and (3) to investigate the association between exercise, total physical activity and good self-rated health. METHODS: A simple random sample of the Swedish population aged 25-64 years were interviewed about their living conditions, health and lifestyle in a survey performed by Statitics Sweden. In total 1876 women and 1880 men completed the survey during 1999 (response rate 76.6%) when two different questions about physical activity assessed exercise and total physical activity in all domains (e.g. transportation, exercise, and at work). Logistic regression models were used to estimate odds ratios. RESULTS: The most inactive individuals (no exercise and total physical activity

Ethnic variations in mental health among 10-15-year-olds living in England and Wales: The impact of neighbourhood characteristics and parental behaviour.

Several studies indicate that young people from certain ethnic minority groups in Britain have significant mental health advantages over their White majority counterparts, but the reasons for these differences have not been adequately explored. This work analyses the impact of neighbourhood characteristics, measured by socioeconomic deprivation; crime; living conditions; ethnic density and parenting behaviour on the mental health of young people. To determine the impact of these factors on mental health among young people, geocoded data from waves 1, 3 and 5 of the UK Household Longitudinal Study (UKHLS) are merged with small area statistics from the 2011 census, and multilevel linear regression models are fitted to the sample of 5513 (7302 observations) 10-15-year-olds of varying ethnicity residing in England and Wales. We find that mental health is generally poorer for White British youths, even after accounting for individual/family-level predictors, neighbourhood characteristics and parental behaviour than it is for minority youths. In keeping with results from studies of adult populations, neighbourhoods with high levels of deprivation are associated with poorer mental health. However, some aspects of parenting behaviour appear to have a more significant impact on the mental health of young people from ethnic minority backgrounds than on White British youths. Further research into factors that influence inter-ethnic disparities in mental health among young people is warranted, given that clear differences remain after the models in this study are fully adjusted.

Predicting healthy lifestyle patterns among retirement age older adults in the WELL study: a latent class analysis of sex differences.

OBJECTIVES: The aim of this study was to identify subgroups of retirement age older adults with respect to their lifestyle patterns of eating, drinking, smoking, physical activity and TV viewing behaviors, and to examine the association between these patterns and socio-demographic covariates. METHODS: The sample consisted of 3133 older adults aged 55-65 years from the Wellbeing, Eating and Exercise for a Long Life (WELL) study, 2010. This study used latent class analysis (stratified by sex), with a set of lifestyle indicators and including socio-demographic covariates. Statistical analyses were performed by generalized linear latent and mixed models in Stata. RESULTS: Two classes of lifestyle patterns were identified: Healthy (53% men and 72% women) and less healthy lifestyles. Physical activity, TV-viewing time, and fruit intake were good indicators distinguishing the "Healthier" class, whereas consumption of vegetables, alcohol (men) and fast food (women) could not clearly discriminate older adults in the two classes. Class membership was associated with education, body mass index, and self-rated health. CONCLUSIONS: This study contributes to the literature on lifestyle behaviors among older adults, and provides evidence that there are meaningful sex differences in lifestyle behaviors between subgroups of older adults. From a policy perspective, understanding indicators or "markers" of healthy and less healthy lifestyle patterns is important for identifying target groups for interventions.

Lifestyle predictors of healthy ageing in men.

With ageing populations a major challenge is to maintain physical and cognitive function, quality of life and independence. The literature does not only indicate important gender differences in lifestyle behaviours, but also how these behaviours might affect health outcomes. The current review has a male perspective when exploring lifestyle predictors of healthy ageing, such as physical activity and sedentary behaviours, smoking, diet and alcohol consumption. This review shows that not only do men with healthy lifestyles survive longer, but also with good health and disability is postponed and compressed into fewer years at the end of life. It is also clear that physical activity and smoking in midlife and late adulthood impact and predict healthy ageing in men. However, healthy ageing has no clear phenotypic definition and more research is needed to establish the impact on dietary and sedentary behaviours on healthy ageing in men. Adoption of healthier lifestyles could result in postponement of age associated diseases and/or the slowing down of the ageing process. Consequently, this allows independent living for a longer period of time and would reduce the burden to social and health care sectors.

Associations between health-enhancing physical activity and country of birth among women.

BACKGROUND: The purpose of this study was to examine the association between total self-reported health-enhancing physical activity and country of birth among women living in Sweden. METHODS: Women (age 18 to 65 years) born in Sweden, Finland, Chile, and Iraq were recruited for this cross-sectional study. Data were collected by means of a postal questionnaire including the International Physical Activity Questionnaire (IPAQ-long version). Self-reported physical activity data were converted to MET-minutes per week and analyzed as continuous or categorical scores. A total of 2649 women were included in the analyses. The association between physical activity and country of birth was explored using ordinal logistic regression assuming proportional odds. RESULTS: The total physical activity differed significantly between the countries of birth (P < .001). Women from Finland had significant higher odds and women from Iraq had significantly lower odds for reporting higher levels of physical activity, compared with Swedish-born women. CONCLUSIONS: The direction of the associations between self-reported total health-enhancing physical activity varied by country of birth, which underlines the need to examine physical activity in each minority group separately.
