THE FIVE COUNTRY STUDY 2014 Perceptions of Weight Control, the Causes of Obesity & Support for Nutrition Policies in Five countries Tony Worsley BACKGROUND • Major economic and health changes are taking place in the Asia Pacific Region. • These affect people’s diets (e.g. Moodie et al. 2013, Popkin et al. 2012) • Rising middle class in many countries; successful policies requires civic engagement (Laverack 2010, Lobstein et al. 2013). • Food & nutrition policymakers need to monitor the effects of their policies. • Little is known about food consumers’ views and experiences in these countries. BACKGROUND & AIMS General aims of the survey To describe: 1 Household food providers’ food & health behaviours & habits during the nutrition transition. 2 Their views of food marketing, retailing & consumption, and food policies. Specific aims 1 Their interest in body weight control. 2 Their beliefs about the efficacy of weight control strategies. 3 Their perceptions of the causes of obesity. 4 Their support for food & nutrition policy options. General hypotheses 1 Nutrition-economic transition: economic change drives changes in food consumption & nutrition status. Populations new to ‘global markets’ will be less aware of dangers to nutrition status. Australia & Singapore further into transition than Vietnam, Indonesia and Shanghai, OzSin likely to be more critical than V.I.S. 2 Personal values: Self and other oriented values & Conformity security values (Schwartz POV) Other oriented values will be positively linked to pro health & nutrition views. 3 Demographics: In line with literature, Older people and women more likely to be concerned about factors which adversely affect nutrition status. 4 Ownership of electronic devices, surrogate index of economic transition into ‘consumer society’. Higher electronic devise ownership, higher penetration of consumer society METHODS The samples • Online survey administered by Global Market Insite using their consumer panels. • Approx. 800 respondents in each of Indonesia, Melbourne, Singapore, Shanghai, Vietnam. • Respondents were household food providers, representative of main age groups in each country; approximately 40% were men. • Samples were highly educated (middle class). METHODS Procedure • Respondents contacted by email during December 2013 and January 2014. • Strong data quality checks e.g. rotation of items to avoid order effects. • Points incentives redeemable for small cash amounts. • Quota (convenience) sampling METHODS The Questionnaire • Several sections composed of closed and open ended items: views and experience of food marketing and supermarkets, perceived healthiness of beverages, views of food skills required by consumers, dietary change attempts in previous year, personal values & detailed demographics. • For this presentation: – – – – Weight control issues (based on IFIC 2013) Effectiveness of personal weight control strategies (previous work) Perceived causes of obesity (Hardus et al. 2003) Support for prevention policy options (Hardus et al. 2003) • Binary and 5 point response scales: “%Yes” & % ratings 4+5 (definitely) reported here Food providers’ levels of concern with their body weight (% somewhat + very concerned).

Many were attempting to control their weight. This is similar to the situation in the USA (IFIC 2013) and elsewhere. The effectiveness of personal ways to avoid obesity were sensible and have a supporting evidence base such as the emphasis on physical activities like walking, the avoidance of energydense products and the importance of healthy daily meal patterns such as breakfast taking. Food and health policies could help people do these things. It is important to engage at least part of the population (such as the rising middle class) if food and nutrition policies are to be well founded, well supported and long lasting (Laverack 2010, Lobstein et al. 2013). DISCUSSION (continued) There was much agreement about the principal causes of obesity. Energy dense products were seen to be a common problem. This is similar to concerns expressed by public health nutritionists (e.g. Moodie et al. 2013). However, there were also major national differences, for example: Melbournians and Singaporeans shared similar viewpoints in many areas. The Vietnamese respondents underreported most of the causes of obesity. Lack of awareness of the dangers of obesity was reported most by Indonesians and least by Melbournians. This suggests Vietnamese and Indonesians may be less familiar with this condition. This may relate to the relative recency of the economic and nutrition transitions or to different cultural traditions in this country. Importance of values and beliefs about obesity and weight control in support for policy actions. CONCLUSION There is a need to monitor these perceptions in order to assess the effectiveness of national food policies and to assess the effects of the economic and nutrition transitions. An inaugural meeting to set up a monitoring system will be held in Singapore in October 2014. REFERENCES International Food Information Council (IFIC) (2013).
