Associations between diabetes status and grip strength trajectory sub-groups in adulthood: findings from over 16 years of follow-up in the MRC National Survey of Health and Development

Table 2 Odds ratios for grip strength trajectory class membership by pre-/diabetes status

Grip strength trajectory class membership	Class 1: High			Class 2: Intermediate			Class 3: Low
	N (%)	OR (95% CI)*		N (%)	OR (95% CI)*		N (%)	OR (95% CI)*
		Model A	Model B		Model A	Model B		Model A	Model B
Males (n = 1101)
Pre-/diabetes
Yes (n = 377) ^†	24 (6.4)	-	-	264 (70.0)	0.98 (0.47, 2.01)	0.95 (0.42, 2.11)	89 (23.6)	1.16 (0.57, 2.37)	1.07 (0.45, 2.55)
Females (n = 1162)
Pre-/diabetes
Yes (n = 375) ^†	60 (16.0)	-	-	265 (70.6)	0.98 (0.57, 1.68)	0.99 (0.54, 1.81)	50 (13.4)	1.36 (0.70, 2.64)	0.68 (0.25, 1.84)

*OR: Odds ratios for class membership, using ‘High’ as referent outcome class and ‘no pre-/diabetes’ as reference exposure group. Model A is unadjusted; Model B is adjusted for social class (53 year), physical activity (53 year), smoking status (53 year), waist-hip ratio (53 year) and height (53 year), educational attainment (26 year), diagnoses of cancer (53 year) and ‘severe respiratory symptoms’ (53 year); ^†after imputation (n = 25 imputations)
