| Bernardi et al. 19 (Brazil/2017) |
2,063 individuals, followed from birth to 23-25 years old. Age at outcome assessment: between 23 and 25 years |
Social mobility from childhood to adulthood. In childhood, maternal level of education; in adulthood, participant’s level of education |
BMI: assessed continuously |
Low vs. high socioeconomic status [mean BMI (SD)]: Males: 26.1 (6.8) vs. 25.4 (6.7); Females: 25.1 (7.3) vs. 22.5 (6.7) |
Among women born with normal weight, the BMI was higher in the group with always low socioeconomic status, as compared to the group with always high socioeconomic status. Among those born with low weight, BMI was higher in the group with always low socioeconomic status, as compared to the group with upward mobility. There was no association for men |

| Savitsky et al. 27 (Israel/2017) |
1,132 individuals, followed from birth to 32 years old. Age at outcome assessment: 32 years |
Social mobility from childhood to adulthood. In childhood, parental occupation was used; in adulthood, participant’s level of education and occupation |
BMI: assessed continuously |
Low vs. high socioeconomic status: β (p-value): 1.019 (0.289) |
Individuals with upward mobility had, on average, a higher BMI, as compared to individuals with always high socioeconomic status. Analyses of downward social mobility and always low socioeconomic status were not significant |

| Albrecht & Gordon-Larsen 20 (United States/2014) |
13,701 individuals, followed from 11/20 to 24/33 years old. Age at outcome assessment: between 24 and 33 years |
Social mobility from childhood to adulthood. In childhood, parental level of education was used; in adulthood, the participant’s level of education was used. The mobility was assessed in three generations of immigrants |
BMI: overweight (25.0-29.9kg/m2) and obesity (≥ 30kg/m2) |
Low vs. high socioeconomic status by immigrant generation [mean BMI (SE)]: First: 26.1 (1.84) vs. 24.7 (1.57); Second: 28.3 (1.25) vs. 26.0 (1.03); Third: 29.3 (0.50) vs. 27.7 (0.50) |
In the first generation of immigrants, individuals with upward mobility had a lower BMI mean as compared to those who remained in the low socioeconomic status group. No association was observed with the other generations and with downward and stable high or medium mobility |

| Boylan et al. 21 (Denmark/2014) |
623 adolescents. Followed for 20-22 years (from 17 to 38 years old). Age at outcome assessment: 38 years |
Socioeconomic status accumulation and social mobility from adolescence to adulthood. For socioeconomic status in adolescence, paternal level of education and occupation was used; in adulthood, the participant’s level of education and occupation |
BMI: overweight (25-30kg/m2) and obesity (> 30kg/m2) |
Low vs. high socioeconomic status [OR (CI)]: Males: 1.0 (0.3; 2.9); Females: 2.8 (0.9; 8.3) |
Women with downward socioeconomic status were more likely to be overweight/obese as compared to those who remained in the high socioeconomic status group. The OR of overweight/obesity among women who accumulated low socioeconomic status from 17 to 38 years of age was 3.6 times higher than those who accumulated high socioeconomic status. There was no association for men |

| Padyab & Norberg 26 (Sweden/2014) |
3,340 individuals, followed from birth to 60 years old. Age at outcome assessment: 60 years |
Socioeconomic status accumulation, social mobility and critical period. The three models were assessed with socioeconomic status at 40, 50 and 60 years old. It was assessed by the participant’s occupation |
BMI: assessed continuously |
Low vs. high socioeconomic status [mean BMI (SD)]: Males: 26.1 (3.5) vs. 26.4 (3.5); Females: 26.6 (4.4) vs. 25.3 (3.6) |
Women who kept a low socioeconomic status had a higher BMI average than those who kept high socioeconomic status. Women with no accumulation of socioeconomic status disadvantage had a lower BMI mean than those with accumulation of socioeconomic status disadvantage. At each increase of one unit in the accumulation score, the BMI increased by an average of 0.44kg/m2. The critical period model was not significant |

| Aitsi-Selmi et al. 7 (Brazil/2013) |
2,063 individuals, followed from birth to 23/25 years old. Age at outcome assessment: between 23 and 25 years |
Social mobility from childhood to adulthood assessed by family income |
BMI: assessed continuously |
Low vs. high socioeconomic status [mean BMI (SD)]: Males: 24.8 (4.6) vs. 25.4 (4.7); Females: 24.6 (5.8) vs. 22.6 (4.1) |
Women with upward mobility and who kept a high socioeconomic status had, on average, lower BMI as compared to those who kept a low socioeconomic status. There was no association for men |

| Gustafsson et al. 22 (Sweden/2012) |
863 individuals, followed from 16 to 43 years old. Age at outcome assessment: 43 years |
Critical period assessed from 16 to 43 years old and socioeconomic status accumulation assessed by number of times with low socioeconomic status (occupation) in all the follow-ups |
BMI: assessed continuously |
Accumulation (R2): Males: 1.0% (age 30 years); Females: 1.0% (age 16 years) and 4.6% (age 43 years). Critical period (low socioeconomic status 16 years): β (CI): Females: mean BMI 30 years: 1.11 (0.43; 1.78); mean BMI 43 years: 2.14 (1.23; 3.06) |
Among women, the accumulation of socioeconomic status disadvantage was associated with the increase in BMI average in all ages studied. For men, only at 30 years, with positive association. Among women, adolescence was considered a critical period for a higher BMI average at 30 and 43 years of age. For men, no critical period was observed |

BMI: assessed continuously |
Mean BMI difference (kg/m2) from non-mobile reference group. Downwardly mobile: 0.68; Upward mean: -0.07 |
Individuals with downward mobility had, on average, a higher BMI as compared to those without social mobility, and individuals with upward social mobility had, on average, a lower BMI as compared to individuals without social mobility |

| Murray et al. 25 (United Kingdom/2011) |
3,035 individuals, followed from birth to 53 years old. Age at outcome assessment: 53 years |
Socioeconomic status accumulation, social mobility and critical period. In childhood, parental occupation was used; in early adulthood and late adulthood, the participant’s occupation |
BMI: assessed continuously |
Low vs. high socioeconomic status [mean BMI (SD)]: Males: 27.9 (4.2) vs. 26.7 (3.8); Females: 28.6 (6.3) vs. 26.0 (4.4) |
Among women, the best model was accumulation of socioeconomic status disadvantage, where at each increase of one unit in the score of accumulation of socioeconomic status disadvantage, BMI increased by an average of 0.91kg/m2 at 53 years. For men, the best model was the critical period (low socioeconomic status in childhood), where individuals with low socioeconomic status in childhood had a higher BMI average |
