Improving health-related quality of life through an evidence-based obesity reduction program: the Healthy Weights Initiative

Figures & data

Table 1 Healthy Weights Initiative – SF-36 dimensions (N=209)

	Baseline, mean (SD)	Follow-up, mean (SD)	Absolute change	Relative change (%)	P-value
Physical functioning	65.9 (22.0)	78.0 (17.4)	+12.1	15.5	0.000
Less role limitations due to physical health	61.8 (35.6)	74.4 (33.3)	+12.6	16.9	0.000
Pain	63.8 (22.5)	70.0 (21.1)	+6.2	8.9	0.000
General health	51.2 (21.3)	64.1 (19.6)	+12.9	20.1	0.000
Vitality	43.3 (17.7)	61.3 (18.1)	+18.0	29.4	0.000
Social functioning	71.1 (24.1)	79.5 (18.2)	+8.4	10.6	0.000
Less role limitations due to emotional health	68.7 (34.9)	76.5 (30.4)	+7.8	10.2	0.000
Emotional well-being	64.3 (18.6)	73.7 (13.2)	+7.6	12.8	0.000

Notes: Higher scores indicate improvements on that dimension. SF-36 is the Medical Outcomes Study 36-Item Short-Form Health Survey.

Abbreviation: SD, standard deviation.

Table 2 Percentage of participants whose SF-36 dimensional score improved from baseline to follow-up

	Improved (%)
Physical functioning	71.3
Role limits due to physical health	59.4
Pain	50.7
General health	76.6
Vitality	83.3
Social functioning	47.4
Role limits due to emotional health	76.3
Emotional well-being	72.7

Note: SF-36 represent the Medical Outcomes Study 36-Item Short-Form Health Survey.

Table 3 Independent risk factors for not improving overall SF-36 score from baseline to follow-up

	Odds ratio	95% CI	P-value
Smoking status (baseline)
Smoker	3.75	1.44–9.78	0.007
Social support
No buddy in program	3.70	1.28–10.68	0.015

Notes: Reference categories: smoking status – nonsmoker; social support – buddy attended program. SF-36 represent the Medical Outcomes Study 36-Item Short-Form Health Survey.

Abbreviation: CI, confidence interval.
