Childhood obesity is a complex and multifactorial disease influenced by various factors including behavioral, physical, and psychological conditions. This cross-sectional study aimed to evaluate the impact of maternal and child stress and food addiction on the nutritional status of children with obesity. Children aged 6 to 12 years were divided into Control Group (n = 42) and Obesity Group (n = 68) according to BMI-Z score. Mothers were allocated to their children’s respective groups. Anthropometric measures, body composition, stress levels, and food addiction were evaluated in both children and mothers. Children with obesity exhibited a significantly higher prevalence of food addiction compared to controls (22.1% vs. 2.6%, p = 0.006), while mothers in the control group showed higher stress levels (68.6% vs. 46.3%, p = 0.039). Positive correlations were observed between mother–child pairs for weight (r = 0.433, p < 0.01) and waist circumference (r = 0.461, p < 0.01). In children, food addiction was a significant predictor of BMI-Z scores (adjusted R square = 0.186); however, maternal BMI and stress were more important predictors (adjusted R square = 0.468). These findings highlight the influence of maternal physical and psychological health on childhood BMI-Z scores. Effective interventions should target both mother and child to improve overall health outcomes.

Background/Objectives: Depression, anxiety, and stress are highly prevalent mental disorders worldwide, and food consumption can change in individuals with these conditions. We aimed to assess the food consumption of women with depressive symptoms and compare it to a control without symptoms. Methods: A cross-sectional study was conducted with 96 women, aged 18–59, allocated into two groups: control (n = 62) or depressive symptoms (n = 34). The participants underwent an anthropometric assessment, and food consumption was evaluated using a 24 h food recall and the NOVA classification. Depressive symptoms, anxiety, and stress were measured using the DASS-21 questionnaire. Results: Anthropometric parameters did not differ between the groups. Women with depressive symptoms consumed fewer calories (p = 0.006), carbohydrates (p = 0.014), proteins (p = 0.036), and lipids (0.011) from unprocessed and minimally processed foods (UMPF) compared to the control women. A negative correlation was found between the dietary consumption energy of UMPF and symptoms of depression (r = −0.337; p = 0.001), anxiety (r = −0.262; p = 0.014), and stress (r = −0.260; p = 0.014), as well as a positive correlation between energy intake from ultra-processed foods (UPF) and symptoms of depression (r = 0.218; p = 0.042) and stress (r = 0.227; p = 0.034). Regression analysis showed that depressive symptoms accounted for 7.6% of the lower energy consumption from UMPF. Conclusions: Women with depressive symptoms displayed lower UMPF consumption, and this was negatively correlated with symptoms of depression, anxiety, and stress. Professional dietary advice can improve health status in these patients.

Objective: This study evaluated anthropometric, biochemical, and inflammatory biomarkers, as well as dietary intake in Brazilian children diagnosed with small intestinal bacterial overgrowth (SIBO) and compared them with their counterparts without SIBO. Methods: This was a cross-sectional study with 106 children aged 7 to 10 years. A glucose-hydrogen breath test was performed to diagnose small intestinal bacterial overgrowth (SIBO). Anthropometric and dietary characteristics were assessed. Blood samples were collected and serum biochemical parameters and cytokines were measured. Results: The occurrence of SIBO was 13.2%. Age, BMI, BMI/age WC, BFP, sex and biochemical markers were similar between SIBO-positive and SIBO-negative children (p > 0.05). High consumption of ultra-processed foods tended to be higher in SIBO-positive compared to SIBO-negative children (47.8 ± 8.2 vs. 42.6 ± 9.5, p = 0.06). Serum levels of IL-17 were higher in SIBO-positive than in SIBO-negative children [69.5 (5.4–125.7) vs. 53.4 (2.3–157.7), p = 0.03], while serum levels of IL-10 were lower in SIBO-positive than in SIBO-negative children [2.3 (0.6–7.2) vs. 5.7 (0.5–30.8), p = 0.04]. Finally, in a logistic regression adjusted for sex, BMI and age, consumption of ultra-processed foods (p = 0.03) and IL-6 levels (p = 0.003) were found to contribute to the occurrence of SIBO. Conclusion: this study identified for the first time an occurrence of 13% of SIBO in children living in the northeastern region of Brazil and showed that consumption of ultra-processed foods and serum levels of IL-6 may influence the occurrence of the SIBO in the pediatrics population.
