Do associations between the pubertal timing-related variant in LIN28B and BMI vary across the life course?
A common genetic variant in LIN28B that confers earlier puberty was associated with a prolonged increase in BMI during adolescence and early to mid-adulthood in women only. Such genetic associations may provide insights into the direct effects of pubertal timing on obesity risk.

Simple conclusions on whether supermarkets are good or bad for nutrition and public health are not justified.
