The following figure comes from a study that looked at determinants of weight gain over time in the Swiss population. Researchers followed 4469 participants for an average of 5.5 years. The figure shows the proportion of participants who gained, maintained, or lost weight during the study period as a function of their baseline weight group (normal weight, overweight, obese at baseline). 100% 90% 29% 36% 80% 40% 70% 60% 50% 55% 40% 44% 35% 30% 20% 25% 10% 17% 21% 0% Normal weight Overweight Obese Weight gain>=kg Weight gain <5kg weight loss From: Guerra, Filipa, et al. "Socio-demographic and behavioural determinants of weight gain in the Swiss population." BMC Public Health 15.1 (2015): 73. What percentage of participants who were obese at baseline gained >=5 kg during the study? Enter as a whole number without the percent sign. Answer: 25 What percentage of participants who were normal weight at baseline gained >=5 kg during the study? Enter as a whole number without the percent sign. Answer: 17 Calculate the risk ratio that compares obese to normal weight participants on the outcome of gaining >=5kg during the study. (Treat the outcome as binary: Participants either gained >=5 kg or did not.) Round to 1 decimal place. Answer: 1.5 Calculate the odds ratio that corresponds to the risk ratio you calculated in (c).
