The association between self-reported diet quality and health-related quality of life in rural and urban Australian adolescents

OBJECTIVE: This study examines the relationship between diet quality and health-related quality of life (HRQoL) in rural and urban Australian adolescents, and gender differences.

DESIGN: Cross-sectional.

SETTING: Secondary schools.

PARTICIPANTS: 722 rural and 422 urban students from 19 secondary schools.

MAIN OUTCOME MEASURES: Self-report dietary-related behaviours, demographic information, HRQoL (AQoL-6D) were collected. Healthy and unhealthy diet quality scores were calculated; multiple linear regression investigated associations between diet quality and HRQoL.

RESULTS: Compared to urban students, rural students had higher HRQoL, higher healthy diet score, lower unhealthy diet score, consumed less soft drink and less frequently, less takeaway and a higher proportion consumed breakfast (P < 0.05). Overall, males had higher unhealthy diet score, poorer dietary behaviours but a higher HRQoL score compared to females (P < 0.05). In all students, final regression models indicated: a unit increase in healthy diet score was associated with an increase in HRQoL (unstandardised coefficient(B)±standard error(SE); B = 0.02 ± 0.01(SE); P < 0.02); and a unit increase in unhealthy diet scores was associated with a decrease in HRQoL (-0.01 ± 0.00; P < 0.05). In rural students alone, a unit increase in unhealthy diet score was associated with a decrease in HRQoL (B = -0.01 ± 0.00; P = 0.002), and in urban students a unit increase in healthy diet score was associated with an increase in HRQoL (B = 0.02 ± 0.00; P < 0.001).

CONCLUSIONS: Cross-sectional associations between diet quality and HRQoL were observed. Dietary modification may offer a target to improve HRQoL and general well-being; and consequently the prevention and treatment of adolescent health problems. Such interventions should consider gender and locality.

Does the poor quality of Australian health education documentation undermine the message? A review of documents informing pregnant women about alcohol

Background. The advice given to pregnant women about alcohol consumption during pregnancy is variable across countries and within countries.Aim. The aim of this study was to review the content and design of existing Australian health education documentation regarding alcohol consumption in pregnancy that is available to pregnant women. Methods. A documentary analysis was conducted. This involved the identification and collection of a range of health education documents, which were then systematically analysed. The thematic and symbolic elements of each document were compared and contrasted using a modified version of the DISCERN instrument. Findings. A total of 32 documents were retrieved via general and targeted internet searching. Documents varied considerably in their purpose, language levels, accessibility, and quality. The majority of documents scored as low to moderate quality. Implications. Although there are many and varied existing documents relating to alcohol consumption during pregnancy in Australia, these are not of high quality and could be substantially improved by including publication dates, using simple language, and providing sources of information. This may result in a more effective public health message and so help to reduce the number of pregnant women who continue to drink during pregnancy.
