Features of your own investigation inhabitants

All round properties of one’s full studies inhabitants, male participants and you will ladies people get when you look at the table 1. From the overall inhabitants, the latest indicate delivery lbs are step 3.3 kg, and you may try a bit large during the males compared to people (step three.3 and you may step three.dos kg, respectively). The fresh frequency of being heavy and over weight are high within the males than in ladies (overweight: 14.0%, ten.6% respectively; obesity: 14.7%, eleven.3% respectively). The brand new suggest beliefs (SD) out of FMI in the kids try 5.8 (±2.5) kg/m dos regarding total inhabitants, 5.0 (±2.5) kg/m dos for the people and you will 6.eight (±2.2) kg/meters dos in women. This new suggest opinions (SD) away from LMI is actually 15.0 (±2.1) kg/yards dos throughout the overall populace, 16.0 (±2.0) kg/m 2 within the men and you may thirteen.8 (±step one.5) kg/meters dos in females.

Table 2 describes characteristics of three groups: those with complete data (n=884), those with missing values on birth weight or BMI (n=206) and those with missing values on DXA (n=420). There were no significant differences in the distribution of characteristics, including birth weight, BMI, FMI and LMI among the three groups. However, those without birth weight or BMI data had higher percentage of those living in the capital area, and being in the lowest tertile of household income compared with those with complete data. Furthermore, both of the distribution of area of residence and household income differed significantly from the complete case (P<0.01 for both area of residence and household income).

BMI of adolescents tended to increase linearly with increasing birth weight in total participants, men and women (P for trend: <0.01, 0.01 and 0.05, respectively) as presented in figure 2. Table 3 shows the total and sex-stratified ORs of being overweight and being obese according to birth weight. In the total population, the unadjusted OR for overweight in the high birth weight group (highest 25th percentile group) was 1.87 (95% CI 1.17 to 2.97) compared with the reference group. In the adjusted analysis, the high birth weight group also had higher risk of being overweight (aOR 1.75, 95% CI 1.11 to 2.76) compared with the reference group. In men, the unadjusted OR for being overweight was 2.32 (95% CI 1.30 to 4.16), and the association remained significant after adjustment of covariates (aOR 2.19, 95% CI 1.20 to 3.98). However, there was no association between high birth weight and obesity in men (aOR 1.16, 95% CI 0.62 to 2.18). In contrast, in women, adjusted analysis demonstrated the association between high birth weight and being obese after adjustment (aOR 2.13, 95% CI 1.03 to 4.41), but no association with being overweight (aOR 1.05, 95% CI 0.47 to 2.37). After data imputation, results that were significant in the complete case analysis remained consistent. In the total population and male population, the high birth weight group had higher risk of being overweight (aOR 1.70, 95% CI 1.08 to 2.54; aOR 2.12, 95% CI 1.17 to 3.99) compared with the reference group after adjustment. In female population, high birth weight group had higher risk of being obese (aOR 2.18, 95% CI 1.11 to 4.49) compared with the reference group after adjustment.

Least squares means of bmi overall members (n=1304), male (n=693) and you can ladies (n=611). We adjusted to possess many jak sprawdzić, kto cię lubi w getiton bez płacenia years, intercourse, residence and you will household income based on beginning pounds.

Relationship between beginning pounds and the entire body constitution

The associations between birth weight, fat mass and lean mass are presented in figure 3 (total participants), figure 4 (men) and figure 5 (women). After adjusting for sociodemographic factors, the adjusted mean values of FMI increased significantly with increasing birth weight in the total population (P for trend: 0.03). However, LMI showed no significant increase with increasing birth weight (P for trend: 0.08). In male participants, higher birth weight was neither associated with higher FMI nor LMI (P for trend: 0.20, 0.25, respectively). In female participants, higher birth weight was associated with higher FMI (P for trend: 0.03), while LMI showed an inverse U-shape (P for trend: 0.25). Even after imputing the missing data, the overall trend of positive correlation between birth weight and FMI did not change. In women and the total population, FMI increased significantly with increasing birth weight (P for trend: <0.01 for both women and the total population). However, LMI did not increase with increasing birth weight (P for trend: 0.20).
