Understanding personal, social and environmental influences on nutrition and physical activity among older adults living in urban and rural areas

肥胖、不良饮食和缺乏身体活动对身体、心理和社会福祉产生负面影响，与这些负担相关的国家经济成本巨大。据估计，肥胖及其相关疾病每年要花费澳大利亚医疗服务部门12亿美元。需要了解营养和身体活动行为的可改变决定因素，以便制定有效的干预措施，促进健康和福祉。因此，促进体育活动和健康饮食有可能大大减轻澳大利亚的疾病负担，提高生活质量。

There are negative impacts of obesity, poor diet and physical inactivity on physical, psychological and social wellbeing and national economic costs associated with these burdens are substantial. Obesity and its associated illnesses are estimated to cost Australian health services $1.2 billion a year. An understanding of the modifiable determinants of nutrition and physical activity behaviours is required in order to develop effective interventions to promote health and well-being. Promoting physical activity and a healthy diet thus has the potential to substantially reduce the burden of disease in Australia and improve quality of life.
