The data shown in bold are variables with values of ǀrǀ > 0.30 and p < 0.01. Spearman correlation coefficients were used to analyse levels of plasma glucose and alanine aminotransferase (with non-normal distribution in both males and females). Pearson’s correlation coefficients were used to analyse the normally distributed variables.VC max: maximum value of vital capacity; FVC forced vital capacity; FEV3 forced expiratory volume in 3 s; BMI body mass index; SBP systolic blood pressure; DBP diastolic blood pressure; PP pulse pressure; Hb haemoglobin; TC triglycerides; HDL high-density lipoprotein.
