An examination of the mediating role of salt knowledge and beliefs on the relationship between socio-demographic factors and discretionary salt use: a cross-sectional study

Background Discretionary salt use varies according to socio-demographic factors. However, it is unknown whether salt knowledge and beliefs mediate this relationship. This study examined the direct and indirect effect of socio-demographic factors on salt knowledge and discretionary salt use in a sample of 530 Australian adults.

Methods An internet based cross-sectional survey was used to collect data for this study. Participants completed an online questionnaire which assessed their salt knowledge, beliefs and salt use behaviour. Mplus was used to conduct structural equation modelling to estimate direct and indirect effects.

Results The mean age of the participants was 49.2 years, and about a third had tertiary education. Discretionary salt use was inversely related to age (r=-0.11; p<0.05), and declarative salt knowledge (knowledge of factual information) scores (r = -0.17; p<0.01), but was positively correlated with misconceptions about salt (r = 0.09; p<0.05) and beliefs about the taste of salt (r = 0.51; p<0.001). Structural equation modelling showed age, education and gender were indirectly associated with the use of discretionary salt through three mediating pathways; declarative salt knowledge, misconceptions about salt and salt taste beliefs.

Conclusions Inequalities observed between socio-demographic groups in their use of discretionary salt use can potentially be reduced through targeted salt knowledge and awareness campaigns.

The moderating effects of demographic factors and hukou status on the job satisfaction-subjective well-being relationship in urban China

This study tests the moderating effect of job complexity and social status, proxied by a unique Chinese cultural variable (hukou status), on the relationship between job satisfaction and subjective well-being in urban China. Data on these and a range of demographic variables were collected from 1025 workers in Fujian Province in the People's Republic of China. Results confirm that hukou status does moderate the job satisfaction-subjective well-being relationship in this sample. Several further moderating relationships are also detected. The study adds the empirical literature on job satisfaction and subjective well-being in China and also furthers understanding of the complex relationship between these constructs. © 2011 Taylor & Francis.

The associations of vegetable consumption with food mavenism, personal values, food knowledge and demographic factors

Background: Poor dietary choices, in particular low consumption of fruits and vegetables are associated with the prevalence of diet related diseases. Ways to increase consumption are urgently required. This paper examines the associations of demographic, psychographic and food knowledge variables with reported vegetable consumption. Methods: An online questionnaire was administered in late 2012 to a national sample 2146 Australians who were selected to represent the Australian population in terms of age, sex, education and location of residence. It was divided into sections which assessed food knowledge, food involvement, food mavenism, personal values and personality factors, demographic characteristics and reported consumption of 13 vegetables and the total number of servings of vegetables per day. Principal components analyses of the individual vegetable consumption ratings derived three forms of vegetable consumption scores. These and total serving per day were used as dependent variables in a structural equation model to identify pathways between them and their likely antecedents. Major findings: Three types of vegetable consumption were formed:. Salad vegetables (onion, tomato and lettuce);. Dinner vegetables (carrot, peas and beans); and 'Green' vegetables (cabbage, spinach broccoli and cauliflower). Food mavenism, food knowledge, food involvement and equality-universalist values mediated the relationships between demographics and conscientiousness and the vegetable consumption variables. Conclusions: The three types of vegetable consumption and total servings per day were associated with different antecedent pathways. The mediating roles of food mavenism, food knowledge, food involvement and equality-universalist values may present opportunities for health promotion and the horticultural industry to increase population vegetable intake. Further research is required to test these associations via experimental and longitudinal studies and qualitative investigation of the meaning and place of the three forms of vegetable consumption in people's daily lives is recommended.

Financial, family, and social factors impacting on cardiac rehabilitation attendance

Background
Attendance in phase 2 cardiac rehabilitation program after acute myocardial infarction is poor.

Objective
To identify and explore the demographic factors that influence peoples’ decisions to attend cardiac rehabilitation programs.

Methods
A descriptive-interpretive design was used. Semi-structured interviews were conducted with 10 people post infarction in Victoria, Australia after their first scheduled appointment to attend outpatient cardiac rehabilitation. The interview transcripts were thematically analysed.

Results
The perceived relevance of cardiac rehabilitation related to the context of people’s lives, namely their financial, family and social situation, and how important program outcomes were seen to be relevant to this context.

Conclusion
The findings of this study suggest that there are a proportion of people unlikely to attend outpatient cardiac rehabilitation programs following an AMI despite encouragement to attend. It may be unrealistic to aim for 100% referral and uptake into cardiac rehabilitation programs and therefore an inappropriate endpoint by which to evaluate such programs.

Socio-demographic inequalities in the diets of mid-aged Australian women

Objectives: This study reports on the distributions of food and nutrient intakes by socio-demographic factors for a large population sample of mid-aged Australian women participating in the Australian Longitudinal Study on Women's Health.
Design: This cross-sectional population-based study used the Cancer Council of Victoria food frequency questionnaires to derive estimates of food and nutrient intakes.
Setting: Nationwide community-based survey.
Subjects: A total of 10561 women aged 50-55 y, at the time of the survey in 2001.
Results: Analysis showed favourable patterns of food intake, with frequent consumption of many foods that are promoted as components of a healthy diet (eg, fresh fruit, leafy green and other vegetables, bread, cereals, milk and meat). Intakes of both foods and nutrients varied significantly across socio-demographic groups, with unmarried women, and women in 'labouring' occupations (eg, cleaner, factory worker, kitchenhand) having poorer nutrient intake.
Conclusions: Although many mid-aged women in this sample had generally healthful diets, women in certain socio-demographic groups (particularly unmarried women and those in labouring occupations) had nutrient intakes of concern. As well as helping to address the dearth of current data on dietary intakes in the Australian population, the results highlight the need for continued targeted public health strategies aimed at improving diet of women from the various socio-economic backgrounds.

Low and high birth weight as risk factors for obesity among 4 to 5 year old Australian children : does gender matter?

Studies testing whether birth weight and childhood obesity differ by gender are lacking. We aimed to describe the relationship between birth weight and childhood overweight/obesity and investigate the influence that gender has on this relationship among 4 to 5-year-old children. We performed a secondary analysis of an Australian nationally representative cross-sectional study in 4 to 5-year-old children. The main outcome measure was child overweight and obesity. We found that low birth weight (LBW) was associated with lower risk of overweight/obesity among girls at 4–5 years before (OR 0.50, 95%CI 0.32, 0.77) and after adjusting for socio-demographic factors (OR 0.51 95%CI 0.33, 0.80) and ethnicity (OR 0.52, 95%CI 0.33, 0.81) but was not associated with child overweight/obesity among boys before or after adjustment. High birth weight (HBW) was associated with a higher risk of overweight/obesity among both girls (adjusted OR: 1.76, 95%CI 1.12, 2.78) and boys (adjusted OR: 2.42 95% CI 2.06, 2.86). Conclusion: There are gender differences in the association of birth weight with child overweight/obesity. HBW was associated with a higher risk of child overweight/obesity in boys and girls before and after adjustment for socio-demographic factors. However, LBW was associated with a lower risk of child overweight/obesity in girls but not in boys. These gender differences need to be considered when planning interventions to reduce child overweight/obesity.

Socio-demographic lifestyle and psychological predictors of benzodiazepine and z-hypnotic use patterns

Aims : Risk and demographic factors for benzodiazepine and z-hypnotic use are incompletely understood. The aim of the paper was therefore to investigate socio-demographic, lifestyle and psychological factors predicting onset and differential pattern of prescribed benzodiazepine and z-hypnotic use in a Norwegian population sample.

Methods : This retrospective cohort study obtained socio-demographic, psychological and lifestyle variables from the Nord-Trøndelag Health Study. Information about benzodiazepine prescriptions from the Norwegian prescription database were linked to epidemiological questionnaire data. Benzodiazepine use was classified into single-period, intermittent and chronic use, and high dose use was defined as being prescribed a yearly average above 180 daily defined doses.

Results : Older age, sleep difficulties and smoking were positively associated with all patterns of benzodiazepine use. Male gender was related to a reduced risk of all patterns of use, whereas educational achievement was negatively associated with single-period use. Alcohol consumption, anxiety and tension were positively related to intermittent and chronic use, while exercise was negatively related to chronic use. Smoking, sleep difficulties and old age were positively associated with prescriptions of high benzodiazepine doses, while exercise was associated with lower doses.

Conclusions : Patterns of prescribed benzodiazepine use are linked to demographic, lifestyle and clinical variables. Non-pharmacological treatment for sleep difficulties and smoking cessation may reduce the risk of chronic benzodiazepine use.

Demographic and socio-cultural correlates of medical mistrust in two Australian states:Victoria and South Australia

Studies on medical mistrust have mainly focused on depicting the association between medical mistrust and access/utilization of healthcare services. The effect of broader socio-demographic and psycho-social factors on medical mistrust remains poorly documented. The study examined the effect of broader socio-demographic factors, acculturation, and discrimination on medical mistrust among 425 African migrants living in Victoria and South Australia, Australia. After adjusting for socio-demographic factors, low medical mistrust scores (i.e., more trusting of the system) were associated with refugee (β=−4.27, p<0.01) and family reunion (β=−4.01, p<0.01) migration statuses, being Christian (β=−2.21, p<0.001), and living in rural or village areas prior to migration (β=−2.09, p<0.05). Medical mistrust did not vary by the type of acculturation, but was positively related to perceived personal (β=0.43, p<0.001) and societal (β=0.38, p<0.001) discrimination. In order to reduce inequalities in healthcare access and utilisation and health outcomes, programs to enhance trust in the medical system among African migrants and to address discrimination within the community are needed.

Do sedentary behaviors mediate associations between socio-demographic characteristics and BMI in women living in socio-economically disadvantaged neighborhoods?

Women living in deprived neighborhoods are a risk group for overweight and obesity, particularly during the childbearing years. Several socio-demographic characteristics may compound this risk, but little is known about why this might be the case. Sedentary behaviors are emerging as a socio-demographically patterned risk factor for obesity. The purpose of the present study was to assess socio-demographic differences in sedentary behaviors, and to examine whether these behaviors could explain the relation between socio-demographic variables and BMI (BMI) in this risk group.

Further examination of relationships between events and psychiatric symptoms in adults with intellectual disability

Background: It has been proposed that people with intellectual disability (ID) might be similar to the general population in the way they respond to significant life events. Some preliminary findings have demonstrated that adults with ID who have experienced recent life events have an increased probability of having psychiatric problems. The aims of the present study were to determine whether previous findings can be replicated, and to examine the influence of additional diagnoses associated with ID on the strength of relationships between life event frequency and psychiatric problems.

Methods: Adults with ID (n = 624), living either in staffed community accommodation or in family or foster homes, were assessed on the Developmental Behaviour Checklist for Adults (DBC-A) and a 37-item life events checklist. Carers who knew the person well acted as proxy informants.

Results: People living in staffed accommodation experienced more life events than people living with natural or foster families. Life event frequency predicted DBC-A total score, five of six sub-scale scores, and caseness status, after significant demographic factors were taken into account. However, the strength of correlations between life event frequency and DBC-A total score varied among sub-groups identified by type of developmental disability and level of ID.

Conclusions: Weak but significant associations between emotional and behavioural problems and life events experienced by adults with ID were demonstrated, but it was also shown that the strength of such associations varies among sub-groups of this heterogeneous population. Future research needs to take account of the circumstances surrounding the life changes, the period of time over which changes might have taken place, and the meaning that the person might attach to the changes. Research into the causal relationship between exposure to life events and the onset of psychiatric problems is also warranted.

The cognitive contexts of beliefs about the healthiness of meat

Objective: The overall aim of this study was to examine a variety of belief and demographic factors that are associated with the perception that meat is intrinsically unhealthy.

Design: State-wide survey (written questionnaire) that included questions on meat and nutrition beliefs, perceived barriers and benefits of vegetarian diets, personal values, number of vegetarian friends and family members, and use and trust of health/nutrition/food information sources.

Setting: South Australia.

Subjects: Six hundred and one randomly selected South Australians and 106 non-randomly selected vegetarians and semi-vegetarians.

Results: For all respondents considered as a group, the most important predictors of the belief that meat is intrinsically unhealthy were the perceived benefits of vegetarian diets (all positive predictors). These included: (1) the perceived links between vegetarianism, peace and increased contentment; (2) animal welfare and environmental benefits; and (3) health benefits. There were differences between different dietary groups however. For non-vegetarians, social concerns about vegetarianism (positive) were most important, followed by health and non-health benefits (positive) of vegetarianism. Red meat appreciation was the strongest (positive) predictor for vegetarians, with health benefits of vegetarianism (positive) and education (negative predictor) also important.

Conclusions: The implications of the findings for health and other issues are discussed. Judgements about the healthiness of meat are likely to be related to moral and environmental beliefs and, for non-vegetarians, to social concerns about vegetarianism, in addition to health beliefs. These need to be considered if any attempts are made to influence meat consumption.

Destinations that matter: associations with walking for transport

Associations between access to destinations and walking for transport were examined. Households (N=2650) were selected from 32 urban communities varying in walkability and socio-economic status. Respondents reported perceived proximity of destinations, transport-related walking, reasons for neighbourhood selection, and socio-demographic characteristics. Geographic Information Systems data defined objective measures of access to destinations. Measures of access to destinations were associated with transport-related walking. Associations depended on socio-demographic factors and type of destinations. Workplace proximity was the most significant contributor to transport-related walking, especially among women. Regular walking to work resulted in the accrual of sufficient physical activity for health benefits.

An exploration of sense of community, part 3: dimensions and predictors of psychological sense of community in geographical communities

Within the discipline of community psychology there remains considerable debate as to the latent structure of psychological sense of community (PSOC). One of the few theoretical discussions is that of McMillan and Chavis (1986), who hypothesized four dimensions: Belonging; Fulfillment of Needs; Influence; and Shared Connections. Discussion has also emerged in the literature regarding the role of identification within PSOC. However few studies have empirically investigated the role of identification in PSOC. The current study explored PSOC in a sample of residents of rural, regional and urban geographical communities (N = 669). In an endeavor to clarify the underlying dimensions of PSOC, a test battery included several measures of PSOC as well as measures of identification with the community. The study also examined the role of demographic factors in predicting PSOC. Results provided support for McMillan and Chavis' (1986) four dimensions of PSOC. Further, a fifth dimension emerged, that of Conscious Identification, suggesting that identification is separate to existing dimensions of PSOC. The demographic factors significantly associated with PSOC were type of region, with rural participants displaying higher PSOC than their urban counterparts; participation in local organizations; having children; and a vision of one’s neighborhood as broader than just a street or block. These results, and the implications for PSOC research, are discussed.

Over and undernutrition in the children of Australian immigrants : assessing the influence of birthplace of primary carer and english language use at home on the nutritional status of 4-5-year-olds

Objective. To document the relationship between childhood nutrition status and ethnicity (defined as the birthplace of primary carer and English language use at home) using a nationally representative sample of 4- to 5-year-old children. Design and participants. Cross-sectional population survey of 4 983 4- to 5-year-old children (2 537 boys and 2 446 girls) as part of Wave 1 (2004) of the Longitudinal Study of Australian Children. Main outcome measures. Overweight/obesity and thinness using the newly published body mass index cut-off points of Cole (2007). Results. In total, 20.6% (95%CI 19.5, 21.7) of children aged 4 to 5 years were estimated to be overweight or obese, while 1.0% (95%CI 0.8, 1.3) was thin. Unadjusted analyses showed a significant relationship between childhood overweight/obesity and primary carer's country of birth (χ2=15.9, p<0.01), but the significance became minimal after adjusting for socio-economic and demographic factors. The adjusted model suggests that boys of primary carer's born in Europe (excluding UK and Ireland) were less likely to be overweight/obese than boys whose primary carers were born in Australia, but the overall effect size was negligible. No difference was found for girls. In addition, boys who mainly spoke English at home were less likely to be overweight/obese (OR=0.49; 95%CI 0.27, 0.88; p=0.017) and thin (OR=0.27; 95%CI 0.12, 0.62; p=0.002) than boys who spoke a language other than English at home. No difference was found for girls. Conclusions. There is a relationship between main language spoken at home and nutritional status in 4-5-year-old boys but not girls. The use of English language at home may be a protective factor for normal weight in young boys. After adjustment for socio-economic and demographics characteristics, there was a negligible relationship between overweight/obesity in children and their primary carer's country of birth.

Understanding the older food consumer, present day behaviours and future expectations

The main aim of this study was to determine whether Baby boomers know how they would manage to maintain a healthy diet on lower incomes in retirement. A cross-sectional survey was conducted at two shopping centres in Melbourne, Australia with 352 respondents. Contingency table analyses (using chi-square tests) were used to examine differences in present and future cooking habits between gender, age and socio-economic groups as well as anticipated changes to food shopping if they had less money in the future. The findings suggest that the most common food preparation behaviours were making meals from scratch ingredients (80% of participants) or using a combination of fresh and convenience foods (55% of participants), with socio-economic and demographic factors significantly influencing specific behaviours. Nearly 50% responded that if they had reduced income they would make a change to their food shopping habits. The most common changes were to the types of food purchased and seeking out special offers or cheaper brands. The results suggest that when faced with a lower standard of living, people will make changes to their food consumption habits. The challenge facing health promotion practitioners, is to ensure that these changes are well informed, leading to healthy options.
