Our findings stress the importance of early prevention of overweight and obesity in women of child-bearing age.

Our findings suggest that a disadvantageous body composition is programmed in early life. This may in part underlie the association between maternal obesity and later cardio-metabolic health of the offspring. These findings support the importance of prevention of overweight in women of child-bearing age.

Aims/hypothesis Maternal obesity predisposes offspring to adulthood morbidities, including type 2 diabetes. Type 2 diabetes and insulin resistance have been associated with shortened telomere length. First, we aimed to investigate whether or not maternal obesity influences insulin sensitivity and its relationship with leucocyte telomere length (LTL) in elderly women. Second, we tested whether or not resistance exercise training improves insulin sensitivity in elderly frail women. Methods Forty-six elderly women, of whom 20 were frail offspring of lean/normal weight mothers (OLM, BMI ≤26.3 kg/m 2 ) and 17 were frail offspring of overweight/ obese mothers (OOM, BMI ≥28.1 kg/m 2 ), were studied before and after a 4 month resistance training (RT) intervention. Muscle insulin sensitivity of glucose uptake was measured using 18 F-fluoro-2-deoxyglucose and positron emission tomography with computed tomography during a hyperinsulinaemic-euglycaemic clamp. Muscle mass and lipid content were measured using magnetic resonance and LTL was measured using real-time PCR. Results The OOM group had lower thigh muscle insulin sensitivity compared with the OLM group (p=0.048) but similar whole body insulin sensitivity. RT improved whole body and skeletal muscle insulin sensitivity in the OOM group only (p=0.004 and p=0.013, respectively), and increased muscle mass in both groups (p<0.01). In addition, in the OOM group, LTL correlated with different thigh muscle groups insulin sensitivity (ρ ≥ 0.53; p ≤ 0.05). Individuals with shorter LTL showed a higher increase in skeletal muscle insulin sensitivity after training (ρ≥−0.61; p≤0.05). Conclusions/interpretation Maternal obesity and having telomere shortening were associated with insulin resistance in adult offspring. A resistance exercise training programme may reverse this disadvantage among offspring of obese mothers.

Background: High fructose intake has been suggested to be a key factor that induces nonalcoholic fatty liver disease (NAFLD), but the evidence from large epidemiologic studies is lacking. Objective: We examined the cross-sectional association between fructose intake and NAFLD by using the Fatty Liver Index (FLI) and the NAFLD liver fat score. Trained study nurses measured weight, height, and waist circumference, and body mass index was calculated. Laboratory staff drew fasting blood for measurements of triglycerides and g-glutamyl-transferase. The FLI and the NAFLD liver fat score were calculated on the basis of these measurements. Habitual fructose and other dietary intake over the past year were assessed by using validated and standardized 131-item food-frequency questionnaires. Data were analyzed in a cross-sectional manner by using logistic regression modeling with statistical software. Results: In a model adjusted for age, sex, and energy intake, participants in the highest fructose intake quartile (range: 29.2-88.0 g/d) had lower risk of NAFLD assessed by using the FLI (OR: 0.56; 95% CI: 0.42, 0.75; P-trend , 0.001) and NAFLD liver fat score (OR: 0.72; 95% CI: 0.53, 0.99; P-trend , 0.001) than that of the lowest intake quartile (range: 2.2-15.2 g/d). This association remained after adjustment for educational attainment, smoking, physical activity, and other dietary variables only for the FLI (OR: 0.68; 95% CI: 0.47, 0.84; P-trend , 0.05). Conclusion: Our cross-sectional results did not support the current hypothesis that high intake of fructose is associated with a higher prevalence of NAFLD as assessed by using the FLI and NAFLD liver fat score.

A larger childhood body size was negatively associated with NAFLD outcomes. Individuals who are small during early childhood and obese as adults seem to be at the highest risk of developing NAFLD.

Our findings suggest an important role of continuous supervised resistance training for the prevention of osteoporotic fractures in elderly women with decreased muscle strength.

Bone marrow insulin sensitivity may be an important factor for bone health in addition to bone mineral density especially in insulin resistant conditions. First we aimed to study if prenatal maternal obesity plays a role in determining bone marrow insulin sensitivity in elderly female offspring. Secondly we studied if a four-month individualized resistance training intervention increases bone marrow insulin sensitivity in elderly female offspring and whether this possible positive outcome is regulated by the offspring’s mother’s obesity status. 37 frail elderly females (mean age 71.9 ± 3.1 years) of which 20 were offspring of lean/normal-weight mothers (OLM, maternal BMI ≤ 26.3 kg/m2) and 17 were offspring of obese/overweight mothers (OOM, maternal BMI ≥ 28.1 kg/m2) were studied before and after a four-month individualized resistance training intervention. Nine age- and sex-matched non-frail controls (maternal BMI ≤ 26.3 kg/m2) were studied at baseline. Femoral bone marrow (FBM) and vertebral bone marrow (VBM) insulin sensitivity were measured using [18F]fluoro-2-deoxy-D-glucose positron emission tomography with computer tomography under hyperinsulinemic euglycemic clamp. We found that bone marrow insulin sensitivity was not related to maternal obesity status but FBM insulin sensitivity correlated with whole body insulin sensitivity (R = 0.487, p = 0.001). A four-month resistance training intervention increased FBM insulin sensitivity by 47% (p = 0.006) only in OOM, while VBM insulin sensitivity remained unchanged regardless of the maternal obesity status. In conclusion, FBM and VBM glucose metabolism reacts differently to a four-month resistance training intervention in elderly women according to their maternal obesity status.Trial RegistrationClinicalTrials.gov NCT01931540

The sex-specific differences for the association between birth-weight and adult RMR might partly be explained by differences in the developmental programming of the sympathetic nervous system between men and women. The higher adjusted RMR among those with the lowest birth-weights is consistent with previous evidence of higher sympathetic drive among these individuals.
