    1. 1. Obesity, Exercise & Men Professor Philip Morgan Priority Research Centre in Physical Activity and Nutrition University of Newcastle
    2. 2. Background 2 • “Over the last 30 years, the average male BMI of Australasian men is increasing faster than for men in almost all other high-income countries.” (Finucane et al. 2011, Lancet) • • • • 70% overweight/obese 95% inadequate F & V intake <50% sufficiently active 20hrs p/wk screen time ABS (2013)
    3. 3. Exercise and weight loss: sex differences? • Sex-specific hormonal, metabolic (> kJ burnt), & appetite responses to PA • Gender-specific recommendations? Hagobian et al. (2013) Curr Obes Rep (2), 86–92 Hagobian et al. (2010) Exerc Sport Sci Rev 38(1): 25-30 Engaging men in PA and weight loss • Prefer to control weight through exercise (Kiefer et al., 2005): seek ‘masculine’ activities (Lewis et al., 2011) • Need for targeted interventions – weight control as motivator (Aoun et al., 2002). Programs have not appealed (Pagoto et al. 2012, Obesity) • Evidence for male-only programs is limited (Young et al. 2012, Obes Rev; George et al., 2012, Sports Med) 3

    9. 9. Findings • Dads experienced improvements in health outcomes (weight, waist, RHR, SBP, PA, dietary), maintained at 6-mth follow up • Behavioural changes (diet & PA) & reduced adiposity (BMIz) in children PA improvement explanation: • Dads: PA mediated weight loss • Children: Co-PA mediated PA 9
