Regression models included log-transformed fatty acid variables. The results presented were backtransformed.
Unadjusted models included a variable for the laboratory analyzed the sample.
Adjusted models included education, smoking, maternal age, parity, income, estimated daily dietary intake of ω-3 or ω-6 fatty acids (depending on the model), and laboratory.
The ω-6:ω-3 ratio was not log-transformed when included in regression models. Results can be interpreted as a 1-point increase in Center for Epidemiologic Studies Depression Scale score corresponding to a 1-unit increase in ω-6:ω-3.
