Associations of a healthy lifestyle score from childhood to adulthood with subclinical kidney damage in midlife: a population-based cohort study

Table 1 Classification of healthy lifestyle factors for children and adults

	Poor (Score = 0)	Intermediate (Score = 1)	Ideal (Score = 2)
BMI ^a
Children 9–15 years	Obese	Overweight	Normal
Adults> 18 years	≥30.0 kg/m²	25.0–29.9 kg/m²	< 24.9 kg/m²
Smoking
Children 9–15 years	> 10 puffs in my life	A few puffs/< 10 puffs in my life	Never smoke in my life
Adults> 18 years	Current smoker	Former smoker	Never smoke
Alcohol consumption
Children 9–15 years	1–7 days/week	Less than once/week	Never
Adults> 18 years	> 20.0 g/day	0.1–20.0 g/day	0 g/day
Physical activity
Children 9–15 years	0–29.9 min moderate or vigorous activity every day	30.0–59.9 min moderate or vigorous activity every day	≥60.0 min moderate or vigorous activity every day
Adults> 18 years	0–74.9 min/week moderate intensity or 0–37.4 min/week vigorous intensity or 0–74.9 min/week moderate or vigorous intensity	75.0–149.9 min/week moderate intensity or 37.5–74.9 min/week vigorous intensity or 75.0–149.9 min/week moderate or vigorous intensity ^c	≥150.0 min/week moderate intensity or ≥ 75.0 min/week vigorous intensity or ≥ 150.0 min/week moderate/vigorous intensity
DGI ^b
Children 9–15 years	<25th percentile	25-75th percentile	≥75th percentile
Adults> 18 years	<25th percentile	25-75th percentile	≥75th percentile

^aIn childhood, overweight and obese were defined according to international standard age- and sex-specific body mass index (BMI) cut-points at each age [21]
^b The dietary guideline index (DGI) comprises nine indicators reflecting 2013 Australian Dietary guidelines. Seven indicators, worth 10 points each, related to recommended minimum intakes (dietary variety, vegetables, fruit, grains, lean meats and alternatives, low-fat dairy and alternatives, water). Two indicators were for limiting intake of discretionary foods (worth 20 points) and replacing saturated fats with unsaturated fats (10 points). The sum of nine components provides a score out of 100, and a higher score indicates better diet quality [22]
^c Minutes of vigorous activity are equal to 2× minutes of moderate activity when moderate and vigorous activities are combined
