The GSHS (http://www.who.int/chp/gshs/en/) currently has data on about 80 countries for children aged 13 to 17 years, with other surveys planned [67],1 The key topics addressed by the GSHS are: alcohol use, dietary behaviours, drug use, hygiene, mental health, physical activity, protective factors, sexual behaviours, tobacco use, and violence and unintentional injury. The questionnaire includes one item on food insecurity: "During the past 30 days, how often did you go hungry because there was not enough food in your home?" For example, for India in 2007, the (weighted) prevalence of the last three responses together was 17.1%. Some of the countries have national datasets but others have datasets only for certain areas of the country.
