Background: Greater lactation duration has been associated with lower incidence of the metabolic syndrome, and self-reported type 2 diabetes and heart disease in women later in life. Two retrospective studies reported higher carotid artery intima-media thickness among parous women who never or inconsistently breastfed, but no clear association with duration. However, lactation history was recalled many years later and heart disease risk factors were not measured before pregnancy. We hypothesized that lactation duration has a graded inverse association with subclinical atherosclerosis in women during mid-life independent of pre-pregnancy cardiometabolic risk factors. Methods: We examined 846 women (46% Black), aged 18-30 years at enrollment in 1985-1986 (baseline) in the biracial Coronary Artery Risk Development in Young Adults (CARDIA) study. Women included delivered 1 or more live births from 1986-2005, had no history of heart disease or diabetes before pregnancies, and had maximum common carotid intima media thickness (ccIMT, mm) measured in 2005-2006 at ages 38-50 years. Lactation duration was recalled within 1 to 4 years of delivery. We categorized women into four lactation groups according to cumulative duration for all post-baseline births; 0-<1 month (n=262), 1-<6 months (n=210), 6-10 months (n=169) and >10 months (n=205). Multiple linear regression models estimated mean ccIMT (95% CI) among lactation categories adjusted for pre-pregnancy cardiometabolic risk factors [BMI, systolic blood pressure (SBP), HDL-C, HOMA-IR], parity, socio-demographics (age, race, education), and smoking. We also assessed weight gain and change in SBP as mediators of the lactation and ccIMT association. Results: Increasing lactation duration showed a graded inverse association with mean ccIMT; differences between >10 months vs. 0<1 month groups ranged from -0.062 from the unadjusted model (p<0.001) and -0.029 from adjusted models (p=0.046) that included pre-pregnancy risk factors and other covariates. Weight gain and SBP change during the 20-year follow up slightly attenuated (~10%) the ccIMT-association with increased lactation duration. Conclusions: Greater lactation duration is associated with lower mean ccIMT independent of cardiometabolic risk factors measured before pregnancy, parity, socio-demographics and smoking. Lactation may have lasting favorable effects on cardiometabolic risk factors for heart disease.

AbstractCentral integration of peripheral neural signals is one mechanism by which systemic energy homeostasis is regulated. Previous work described increased acute food intake following chemical reduction of hepatic fatty acid oxidation and ATP levels, which was prevented by common hepatic branch vagotomy (HBV). However, possible offsite actions of the chemical compounds confound the precise role of liver energy metabolism. Herein, we used a liver-specific PGC1a heterozygous (LPGC1a) mouse model, with associated reductions in mitochondrial fatty acid oxidation and respiratory capacity, to assess the role of liver energy metabolism in systemic energy homeostasis. LPGC1a male mice have 70% greater high-fat/high-sucrose (HFHS) diet-induced weight gain and 35% greater positive energy balance compared to wildtype (WT) (p<0.05). The greater energy balance was associated with altered feeding behavior and lower activity energy expenditure during HFHS in LPGC1a males. Importantly, no differences in HFHS-induced weight gain or energy metabolism was observed between female WT and LPGC1a mice. WT and LPGC1a mice underwent sham or HBV to assess whether vagal signaling was involved in HFHS-induced weight gain of male LPGC1a mice. HBV increased HFHS-induced weight gain (85%, p<0.05) in male WT, but not LPGC1a mice. As above, sham LPGC1a males gain 70% more weight during short-term HFHS feeding than sham WT (p<0.05). These data demonstrate a sexspecific role of reduced liver energy metabolism in acute diet-induced weight gain, and the need of more nuanced assessment of the role of vagal signaling in short-term diet-induced weight gain.Key Points SummaryReduced liver PGC1a expression results in reduced mitochondrial fatty acid oxidation and respiratory capacity in male mice.Male mice with reduced liver PGC1a expression (LPGC1a) demonstrate greater short-term high-fat/high-sucrose diet-induced weight gain compared to wildtype.Greater positive energy balance during HFHS feeding in male LPGC1a mice is associated with altered food intake patterns and reduced activity energy expenditure.Female LPGC1a mice do not have differences in short-term HFHS-induced body weight gain or energy metabolism compared to wildtype.Disruption of vagal signaling through common hepatic branch vagotomy increases short-term HFHS-induced weight gain in male wildtype mice, but does not alter male LPGC1a weight gain.

Background: Little is known about hepatic steatosis (HS) incidence and its relationship to underlying or new-onset cardiometabolic risk. This study aims to assess the incidence of hepatic steatosis in an asymptomatic population and to determine its relationship to both prevalent and new-onset cardiometabolic risk factors. Methods: We analyzed retrospective data from a voluntary employer-sponsored routine health promotion evaluation at the Preventive Medicine Center of the Hospital Israelita Albert Einstein (São Paulo, Brazil) collected from October 2004 to December 2016.Medical and demographic history, anthropometric measures including blood pressure, body mass index (BMI) and waist circumference, and fasting blood samples were obtained. Participants also had ultrasonography to assess for HS. We included data from 8,448 individuals who had complete cardiometabolic and ultrasound data at baseline and repeated all tests at least 6 months later. Results: The mean age (standard deviation, SD) of participants was 40 (9) years. Over a mean (SD) follow-up of 3.4 (2.3) years, the incidence of HS was 14.7%. As shown in the table, diabetes, poor physical activity, elevated waist circumference and cigarette smoking at baseline were independently associated with hepatic steatosis. There was an additive effect of the increasing cardiometabolic risk factors (see graph) on the risk of developing HS. Participants with new-onset cardiometabolic risk factors also had a higher risk of incident HS after accounting for baseline demographics and cardiometabolic risk factors (see forest plot). This was most pronounced for incident obesity (BMI ≥ 30 Kg/m 2 ). Conclusion: In this relatively young population, the incidence of HS was high and was both independently and collectively associated with baseline cardiometabolic risk. New-onset cardiometabolic risk tracks with incident HS. This study emphasizes the need for assessing and mitigating cardiometabolic risk in the prevention of HS.
