Objective: To investigate the association of mental health in childhood and adolescence with four outcomes at 18 years: ultra-processed food (UPF) consumption, body mass index (BMI), excessive weight (EW), and body composition, including fat mass (FM) and fat free mass (FFM) in kg, FM index (FMI) and FFM index (FFMI) in kg/m.
Methods: Cohort study in which The Development and Well-Being Assessment (DAWBA) (6 and 11 years) and the MINI International Neuropsychiatric Interview (MINI) (18 years) provided information on internalizing (INT), externalizing (EXT) and any mental disorder (ANY). The exposure was classified in: "never", "at 6 and/or 11 years", "at 18 years only" and "at 6, 11, and 18 years".
Background: The association of ultra-processed food (UPF) consumption with obesity and adipose tissue in children/adolescents remains poorly understood.
Objective: To assess the association of UPF consumption with excessive weight (EW-defined as BMI-for-age ≥+1 z-score) and body composition at 15 years.
Methods: In a birth cohort, daily UPF consumption was estimated by Food Frequency Questionnaires at 6 and 15 years.
Article Synopsis
- This study aimed to explore the relationship between sleep problems and headaches in 15-year-olds from the Pelotas 2004 Birth Cohort in Brazil.
- A total of 1916 adolescents were analyzed, revealing a headache prevalence of 51.6%, with a notable difference between genders and various types of headaches reported.
- The results indicated that adolescents experiencing insomnia three or more times a week had a significantly higher likelihood of suffering from headaches, highlighting a clear connection between poor sleep and headache prevalence.
Purpose: Our aim was to assess the impact of COVID-19 on depressive symptoms among mothers from a population-based birth cohort in Pelotas, Southern Brazil.
Methods: A subgroup of mothers from the Pelotas 2004 Birth Cohort was assessed pre-pandemic (November,2019 to March,2020) and mid-pandemic (August-December,2021). In both follow-ups, depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS).
