In this regard, Wong et al. (2015), in a sample of middle-aged individuals (n = 490; age = 42.7 +7.4 years) showed SJL was positively associated with fasting insulin (β = 0.11, p < 0.05) and insulin resistance (β = 0.11, p < 0.05), but not with fasting glucose. The gene discussed is INS; the disease is Insulin resistance.
