  1. In the Categories column the regression analyses are categorised by gender (All represents the combined group of men and women); and by identification of obesity (I and NI). Variable refers to the regression coefficients; Unstd. B Unstandardised Beta coefficient, Std. Error standard error, t-statistic, f-statistic, R2, Sig Significance value, 95% C.I. Lower Lower bound of the 95% confidence interval, 95% C.I. Upper Upper bound of the 95% confidence interval. Responses were taken only in the range BMI < 35 to test linearity
