The good news: while obesity rates keep climbing in developed nations, the rate at which they are climbing has slowed down. This according to the latest OECD report on obesity among member nations. Rising obesity rates means rising costs to the economy. But there may also be a strong link from economic struggles to the rise in obesity. From the report: In 2008, the world economy entered one of the most severe crises ever. Many families, especially in the hardest hit countries, have been forced to cut their food expenditures, and tighter food budgets have provided incentives for consumers to switch to lower-priced and less healthy foods. During the 2008-09 economic slowdown, households in the United Kingdom decreased their food expenditure by 8.5% in real terms, with some evidence of an increase in calorie intake (the average calorie density of purchased foods increased by 4.8%). This change resulted in additional 0.08 g of saturated fat, 0.27 g of sugar and 0.11 g of protein per 100 g of purchased food (Institute for Fiscal Studies, Briefing Note No. 143). A similar trend was observed in Asian countries experiencing a recession in the late 1990s, with consumers switching to foods with a lower price per calorie (Block et al., 2005, Economics and Human Biology; World Bank, 2013, Working Paper No. 6538). Between 2008 and 2013, households in Greece, Ireland, Italy, Portugal, Spain and Slovenia decreased slightly their expenditure on fruits and vegetables, while households in other European OECD countries increased it at an average of 0.55% per year (OECD/ Imperial College analyses of passport data, Euromonitor International). Fruit and vegetable consumption was inversely related with unemployment in the United States, in the period 2007-09, and the effect was three times stronger in disadvantaged social groups at higher risk of unemployment (corresponding to a 5.6% decrease in fruit and vegetable consumption for each 1% increase in state-level unemployment). Given the size of job losses at the peak of the crisis, the most vulnerable groups may have reduced their consumption by as much as 20% (Dave and Kelly, 2012, Social Science and Medicine). Evidence from Germany, Finland and the United Kingdom shows a link between financial distress and obesity. Regardless of their income or wealth, people who experience periods of financial hardship are at increased risk of obesity, and the increase is greater for more severe and recurrent hardship (Munster et al., 2009, BMC Public Health; Conklin et al., 2013, BMC Public Health; Laaksonen et al., 2004, Obesity Research). An Australian study found that people who experienced financial distress in 2008-09 had a 20% higher risk of becoming obese than those who did not (Siahpush et al., 2014, Obesity). Financial hardship affects all household members. American children in families experiencing food insecurity are 22% more likely to become obese than children growing in other families (Metallinos-Katsaras et al., 2012, Journal of the Academy of Nutrition and Dietetics). While some evidence suggests that shorter working hours and lack of employment are associated with more recreational physical activity (Tekin et al., 2013, NBER Working Paper No. 19234), at times of increasing unemployment any gains are likely to be offset by reduced work-related physical activity. In the United States, in the aftermath of the economic crisis, leisure-time physical activity increased by three METs (metabolic equivalents – a measure capturing both duration and intensity of physical activity) but work-related physical activity decreased by 19 METs (Colman and Dave, 2013, NBER Working Paper No. 17406). In summary, the evidence of a possible impact of the economic crisis on obesity points rather consistently to a likely increase in body weight and obesity. Download the full report here .
