Table 3. Odds ratio (ORs) and 95% confidence interval (CI) in statistical modeling to test the effects of cumulative frequency of geographic relocation (CFGR) with self-rated mental health.

Frequency		Negative self-rated mental health
		ORb [95% CI]	ORc [95% CI]	ORd [95% CI]
		Model Aa Residential mobility (categorical comparisons)
		CFGR 1 (Before age 18 years)	≥3 vs. 0	2.03 [1.10–2.70]	1.72 [1.52–2.31]	1.70 [1.52–2.35]
	1–2 vs. 0	1.22 [0.82–1.64]	1.13 [0.84–1.52]	1.13 [0.79–1.59]
CFGR 2 (Age 18 to 5 years ago)	≥3 vs. 0	1.25 [0.92–1.76]	1.23 [0.88–1.79]	1.23 [0.84–1.85]
	1–2 vs. 0	0.71 [0.43–1.07]	0.71 [0.42–1.07]	0.75 [0.44–1.17]
CFGR 3 (During the most recent 5 years)	≥1 vs. 0	1.83 [1.32–2.73]	1.82 [1.28–2.76]	1.73 [1.22–2.67]
Model B Residential mobility (increase per time)
Total CFGR		1.20 [1.10–1.25]	1.07 [1.02–1.15]	1.06 [1.02–1.16]
Add social support
Negative relations with extended family (y/n)			2.96 [2.04–4.31]	2.31 [1.37–3.24]
Negative relations with friends (y/n)			3.11 [2.08–4.64]	2.71 [1.77–4.14]
Add satisfaction with residential environment in past and current living places
RES1: Poor → Poor vs. Good → Good				2.89 [1.15–6.46]
RES2: Good → Poor vs. Good → Good				6.26 [3.98–9.83]
RES3: Poor → Good vs. Good → Good				1.31 [0.86–1.98]
RES1 × Total mobility				1.34 [1.06–1.70]
RES2 × Total mobility				1.56 [0.92–3.05]
RES3 × Total mobility				0.86 [0.73–0.95]

^aOnly final models are presented for inferences regarding the 3 CFGR categories (categorical comparisons).

^bAdjusted model 1: adjusted for demographic characteristics by propensity score analysis.

^cAdjusted model 2: adjusted for social network support.

^dAdjusted model 3: adjusted for residential environmental satisfaction.
