Table 3. Association of Actual Receipt of the Health Guidance Intervention With Health Outcomes (2017-2018 Data)^a.

Outcome	1 y after (2018) (n = 39 161)	P value
Change in weight
Body weight, kg	−1.56 (−3.10 to −0.22)	.02
BMIb	−0.61 (−1.19 to −0.14)	.01
Waist circumference, cm	−0.44 (−2.03 to 1.69)	.86
Change in cardiovascular risk factors
Blood pressure, mm Hg
Systolic	−2.32 (−10.16 to 4.60)	.46
Diastolic	−0.37 (−5.30 to 4.94)	.94
Hemoglobin A1c, %	0.10 (−0.10 to 0.31)	.32
LDL cholesterol, mg/dL	6.19 (−4.16 to 20.60)	.19

Abbreviations: BMI, body mass index; LDL, low-density lipoprotein; NA, not applicable.

^a We used the bandwidth of regression discontinuity design of 6 cm from the threshold of waist circumference. Analyses were adjusted for age, lifestyle variables (current smoking, alcohol use, exercise habits), systolic blood pressure, diastolic blood pressure, hemoglobin A_1c level, LDL cholesterol level, and drug use (antihypertensive drugs, antidiabetic drugs, and antihyperlipidemic drugs).

^b Calculated as weight in kilograms divided by height in meters squared.

SI conversion factors: To convert LDL cholesterol to mmol/L, multiply by 0.0259. To convert percentage of total hemoglobin to proportion of total hemoglobin, multiply by 0.01.
