Background And Aim: Parabens are widely used as antimicrobial preservatives in personal care products. Studies investigating obesogenic or cardiovascular effects of parabens show discordant results, while data on preschool children are lacking. Paraben exposure during early childhood could have profound cardiometabolic effects later in life.

Methods: In this cross-sectional study paraben concentrations [methyl (MeP), ethyl (EtP), propyl (PrP), butyl (BuP)] were measured by ultra-performance liquid chromatography/tandem mass spectrometry in 300 urinary samples of 4-6-year-old children of the ENVIRONAGE birth cohort. Paraben values below the limit of quantitation (LOQ) were imputed by censored likelihood multiple imputation. The associations between log-transformed paraben values and cardiometabolic measurements (BMI z-scores, waist circumference, blood pressure and retinal microvasculature) were analyzed in multiple linear regression models with a priori selected covariates. Effect modification by sex was investigated by including interaction terms.

Results: Geometric means (geometric SD) of urinary MeP, EtP, and PrP levels above the LOQ were 32.60 (6.64), 1.26 (3.45), and 4.82 (4.11) μg/L, respectively. For BuP more than 96% of all measurements were below the LOQ. Regarding the microvasculature, we found direct associations between MeP and central retinal venular equivalent (β = 1.23, p = 0.039) and PrP with the retinal tortuosity index (x10(β = 1.75, p = 0.0044). Furthermore, we identified inverse associations between MeP and ∑parabens with BMI z-scores (β = -0.067, p = 0.015 and β = -0.070, p = 0.014 respectively), and EtP with mean arterial pressure (β = -0.69, p = 0.048). The direction of association between EtP and BMI z-scores showed evidence for sex-specific differences with a direct trend in boys (β = 0.10, p = 0.060).

Conclusions: Already at young age paraben exposure is associated with potentially adverse changes in the retinal microvasculature.

Although positive coparenting, or how parents relate during childrearing, is known to support children's socioemotional development, the role of coparenting in supporting children's healthy eating and growth is poorly understood. This study examined associations between coparenting quality, the home food environment, and young children's body mass index (BMI). Cross-sectional data were obtained from 290 mothers and their 3-year-old children who participated in the Sprout study.

Introduction: Adolescence is a phase of life marked by rapid growth. Adequate nutrition is essential during this developmental stage, leading to significant physical performance, improved cognitive ability, and productivity. Improving adolescent girls' nutrition is crucial for breaking the intergenerational cycle of malnutrition, but research in Pakistan has largely focused on children under five and pregnant women, often neglecting this vulnerable group.

Introduction Osteoporosis mainly affects postmenopausal women and is characterized by decreasing bone mass and an increased risk of fracture. As populations age, it becomes more common and is frequently missed until fractures happen. Simultaneously, there is conflicting evidence about the relationship between bone health and diabetes, a chronic metabolic illness, with varying effects on the skeletal system.

This study aims to explore the long-term physical, neurological, social and emotional development outcomes of the offspring born to patients with systemic lupus erythematosus (SLE), and to provide insights that can assist pediatricians in enhancing the long-term prognosis of these children. We conducted a cross-sectional study on the offspring of SLE patients who had undergone pregnancy and were admitted to our obstetrics department between January 1, 2016 and September 30, 2021. The control group consisted of offspring born to mothers without connective tissue disease, and was matched 1:1 based on age (birth date ± 1 month) with the offspring of SLE patients.

Background: Understanding the risks and effects of gestational weight gain (GWG) is a prominent area of perinatal research but approaches for quantifying GWG are evolving and remain underdeveloped, especially in clinical settings for underserved demographic subgroups. To fill this gap, we demonstrated and compared six GWG metrics across pre-pregnancy BMI classifications: total GWG, trimester-specific linear rate of GWG, adherence to total and trimester-specific recommendations, area under the curve, and GWG for gestational age z-scores.

Methods: We used clinical data on 44,801 pregnant people from community-based health care organizations with extensive longitudinal measures and substantial representation of understudied subgroups.
