“…There are few studies among Chinese populations examining the role of dietary intake, taking into account other confounding factors such as age, physical activity, gender and educational attainment. Other than the effect of total energy and macronutrient intake (Halkjaer et al, 2006) on development of overweight and obesity, recent studies have highlighted the role of dietary patterns in terms of meal frequency and timing, and types of food consumed (Kirk, 2000;Sichieri, 2002;Francis et al, 2003;Ghosh et al, 2003;Kelishadi et al, 2003;Nicklas et al, 2003;Waller et al, 2003;Bazzano et al, 2005;Hubert et al, 2005;Howard et al, 2006). For example, patterns predisposing to overweight and obesity include a 'Westernized' pattern compared with a 'traditional' pattern for the population studied (Sichieri, 2002;Ghosh et al, 2003;Hubert et al, 2005) and snacks consumption (Fu and Hao, 2002;Francis et al, 2003;Sothern, 2004;Hubert et al, 2005).…”
