Obese adults have more chronic health problems than smokers, heavy drinkers or the poor, according to a US study.
The report by the RAND institute in Santa Monica, California, found that obese people had on average nearly twice the chronic health troubles of people of normal weight.
The study also found that smoking harmed the health of women more than men, with female smokers having about 40% more chronic health problems than non-smokers. The figure was 30% for men.
