Table 3. Morbidity pattern of the study groups.

Morbidity pattern	Train drivers n=100	Comparison group n=100	Test of significance and P value
Morbidity pattern	N (%)	N (%)	Test of significance and P value
Obesity	62(62)	12(12)	χ ²=53.63, P≤0.001
Hypertension ^b	46(46)	16(16)	χ ²=21.03, P≤0.001
Dyslipidemia ^c	67(72.8)	33(35.5)	χ ²=25.97, P≤0.001
Psychological distress	71(71)	27(27)	χ ²=38.74, P≤0.001

^{^b}

Hypertension cases (46 vs. 16) = previously diagnosed cases of HTN (26 vs. 11) - in addition to newly discovered cases of HTN (20 vs. 5).

^{^c}

Participants who accepted to give a blood sample for laboratory investigation - train drivers (n=92) & comparison group (n=93).
