have different behaviours according to age: men increase their participation in both walking and other moderate PA; women seem to replace walking with other moderate PA from age 65 to 69. The reasons for these changes are not clear. Research and interventions around these points is warranted in order to develop effective health promotion strategies.

of Western Australia 2 Western Australian Centre for Health & Ageing, The University of Western Australia Introduction: Given the ageing population, physical activity (PA) promotion strategies targeting older adults are required. Many studies, however, treat “older adults” as one cohesive group, although behaviours may vary. In Australia, few studies have examined PA behaviours of older adults. The Baby Boomers and Beyond study examined PA behaviours of older Western Australians and the underlying gender and age differences. Methodology: Secondary analyses were undertaken of a cross-sectional survey conducted in 2006 by the Premier’s Physical Activity Taskforce, Government of WA, restricted to adults aged 45 years and over (n = 2081). Respondents were stratified into 5-year age groups. Sufficient PA was defined according to Active Australia guidelines (= 150 min of PA weighted per week: minutes of moderate PA (or walking) and 2 × minutes of vigorous PA). General linear models were estimated to investigate the average time spent on walking, other moderate PA and vigorous PA among men and women by age. Main and interaction effects of age and gender were tested, while controlling for geographical region and body mass index. Results: Up to age 65–69, the proportion of sufficiently active persons was constant (61–63%). From age 70–74 there was a decline, with more people insufficiently active. From age 80, further decline occurred, with the proportion of inactive persons doubling. The time women spent on walking remained constant up to age 60–64 and decreased thereafter. Men increased the time spent on walking up to age 70 to 74, followed by a steep decrease. The main effect of age was significant (p < .05), as was the age-gender interaction (p < .05). Across all age groups, men spent more time on other moderate PA than women. Despite a small dip for women aged 55–64, both showed an increase in such PA up to age 75–79. The main effects of both age (p < .001) and gender (p < .001) were significant, as was the age-gender interaction (p < .05). For time spent on vigorous PA, no significant gender and age differences were found. Conclusions: The study shows that overall participation in PA drops from age 70–74. Moreover, men and women

Central Queensland University, Institute for Health and Social Science Research Purpose: A sufficient level of physical activity (a minimum of 30 minutes of moderate intensity physical activity at 5 or more days per week) is important for good health. Surveillance and monitoring of population levels of physical activity can provide estimates of health care costs and indicate whether health promotion efforts are needed, or if past efforts have been effective. The objective of this study was to determine the changes in the prevalence of physical activity in Central Queensland over the period 2002–2008. Methods: Data was obtained from the Central Queensland Social Survey conducted annually from 2002 to 2008. A total sample of 8936 adults aged 18 and over participated in 7 cross-sectional CATI surveys. The number of participants for each survey year ranged between 1243 and 1316. Samples were weighted to match the ABS census data for Queensland on age and geographical location. Physical activity was measured using the Active Australia Questionnaire and standard protocols where used to calculate sufficient physical activity. Logistic regression was used to examine trends in the prevalence of sufficient physical activity across years; the analysis was adjusted for gender, age, education and BMI. Results: The proportion of adults achieving sufficient physical activity slowly but steadily increased across 2002 (44.1%), 2003 (47.2%), 2004 (46.3%), 2005 (46.6%), 2006 (48.8%) and 2008 (53.3%); however an unexpected large decline occurred in 2007 (39.2%). A small significant upward trend was found for meeting physical activity recommendations across all years (OR = 1.025; 95%CI = 1.01–1.05; P = 0.019), indicating that the odds of meeting the physical activity guidelines increased by 2% per year from 2002 to 2008. The usual differences in socio-demographics were observed (e.g. men are more active than women; younger participants are more active than older participants); and similar changes in prevalence levels across years as those described for the total population were observed across genders, ages, living environments (rural or urban), income levels educational attainment and BMI.

Conclusion: It is positive to note that no overall decline in physical activity was observed across years; however despite state and regional efforts to increase physical activity only a small upward trend in activity levels was observed in Central Queensland. About half of the population remains insufficiently active and more efforts to increase physical activity are needed. doi:10.1016/j.jsams.2009.10.127 127 The prevalence of strength training activities in an Australian population B. Humphries ∗ , M. Duncan, K. Mummery Institute of Health and Social Science Research, Central Queensland University Introduction: The core components of physical activity, cardiovascular endurance, muscular strength, balance, and flexibility, can provide many health benefits and potentially slow declines associated with aging. National health authorities have widely promoted aerobic exercise message to the public, although the promotion of strength training has received far less attention. The primary objective of this research was to determine the prevalence of strength training activities in an Australian population whist examining gender and age trends. The secondary purpose of this research was to ascertain from those individuals currently training if the level of training is sufficient to promote health benefits and meet the recommended guidelines as reported by the American College of Sports Medicine (ACSM). Methodology: A Computer-Assisted-TelephoneInterview (CATI) survey (n = 1235; male = 620, female = 616) conducted by Population Research Laboratory at CQUniversity performed a survey of Central Queensland adults in October-November 2007. Respondents were asked to report on their strength training knowledge, sources of strength training knowledge, participation levels, duration, frequency and intensity of training, and barriers and constraints to engaging in strength training. Participants: Respondents were 18 years of age or older that could be contacted by direct-dialed, land-based telephone service. A telephone database using a computer program to select, with replacement, a simple random sample of phone numbers selected respondents. Results: Almost 80% of the population did not perform strength training, 15% performed strength training but at an insufficient level for health benefits while only 5% performed at a sufficient level. Significantly more males performed strength training and at sufficient levels than females (p = 0.037). Respondents over 65 years were less likely to participate in strength training and less likely to train at sufficient levels than younger cohorts (p = 0.003). From the respondents performing sufficient levels of strength training males trained
significantly more days per week (p = 0.021), numbers of repetitions (p = 0.016) and at a higher intensity (p = 0.022) than females. Strength training participation over 65 years was significantly less for number of days per week (p = 0.004), number of exercises performed (p = 0.017), number of repetitions (p < 0.001) and intensity of training (p < 0.001) than younger cohorts. Conclusions: The present data suggests that the prevalence of Australian’s participating in regular strength training programs is low and unlikely to provide health benefits. The findings also underscore the need to increase overall education on the benefits of regular strength training with an emphasis among targeted adult populations to increase participation in strength training programs. doi:10.1016/j.jsams.2009.10.128 128 A national survey of physical activity behaviour: Preliminary results from the mission-on evaluation in New Zealand R.

Introduction: Mission-On was launched in New Zealand in 2006 and included a package of Government-wide initiatives to help young people improve their understanding and skills related to healthy nutrition and being more physically. It is an inter-agency campaign led by the Sport and Recreation New Zealand (SPARC) in partnership with the Ministry of Health and Ministry of Education, and with support from the Ministry of Youth Development. An evaluation of MissionOn was conducted in 2008/2009. Purpose: To conduct a national survey of New Zealand children and young people’s (1) physical activity and sedentary behaviour patterns; (2) food and nutrition behaviour patterns and; (3) attitudes, awareness, values, and knowledge of Mission-On’s key lifestyle messages. Preliminary physical activity and sedentary behaviour data will be presented. Study design/Methodology: A national representative cross sectional survey of children and young people (CYP) (n = 2500) was undertaken. Face-to-face home interviews with CYP and/or their parents/caregivers were conducted throughout New Zealand. Measures of physical activity and sedentary behaviour were assessed using both objective (accelerometer) and subjective (Multi-media Activity Recall Questionnaire for Children and Adolescents) measures.
