Figure 2: Interaction between BDNF genotypes and PUFA intake on BMI in the BPRHS. Lozenges represent the major allele GG homozygotes ( in men; in women) and triangles the minor allele A carriers (AA homozygotes and GA heterozygotes combined together, in men; women, in women). Predicted BMI values for all subjects participants were plotted against their dietary PUFA intake expressed as the percentage of total energy intake. BMI values were calculated based on a regression model containing PUFA intake, BDNF genotypes, and potential confounders including age, smoking status, drinking status, sex, education, medication use for depression, physical activity, total energy, and population admixture.
