Infant malnutrition remains an important cause of death and disability, and Haiti has the highest prevalence in the Americas. Therefore, preventive strategies are needed. Our aims were (1) To assess the prevalence of malnutrition among young children seen at a health center in Haiti; (2) Examine adherence to infant feeding practices recommended by the World Health Organization (WHO) and the association to nutritional status. This cross-sectional study recruited children from the Saint Espri Health Center in Port Au Prince in 2014. We recorded feeding practices, socio-demographic data, and anthropometric measurements (WHO-2006). We evaluated 278 infants and children younger than two years old, aged 8.08 ± 6.5 months, 53.2% female. 18.35% were underweight (weight/age <−2 SD); 13.31% stunted (length/age <−2 SD), and 13.67% had moderate or severe wasting (weight/length <−2 SD). Malnutrition was associated with male gender, older age, lower maternal education level, and greater numbers of siblings (Chi², p < 0.05). Adherence to recommended breastfeeding practices was 11.8–97.9%, and to complementary feeding practices was 9.7–90.3%. Adherence was associated with a lower prevalence of malnutrition. Conclusion: Prevalence of infant and young child malnutrition in this population is high. Adherence to WHO-recommended feeding practices was associated with a better nutritional status.

Lockdown caused by the COVID-19 pandemic may have influenced feeding behaviour and lifestyle in children and adolescents. The purpose of this study was to analyse feeding behaviour and lifestyle in children and adolescents one year after lockdown by the COVID-19 pandemic in Chile. In this cross-sectional study an online survey was implemented in 1083 parents and caregivers regarding their children’s feeding behaviour and lifestyle and sociodemographic background. The results showed that “eat breakfast daily” (89.2%), “not overnight food intake” (69.9%) and “not fast-food intake” (66.0%) were the most frequent reported feeding behaviours, particularly in pre-school children. Respondents declaring healthy feeding behaviours and lifestyle were 23.4 and 23.7%, respectively, with no significant differences by sex. In pre-school children, families with three or fewer members and parents or caregivers with an undergraduate or postgraduate degree reported a significantly better feeding behaviour and lifestyle compared to families with more than three members and parents or caregivers without an undergraduate or postgraduate degree. In conclusion, the pandemic lockdown had a negative impact in lifestyle in children and particularly in adolescents. Healthier feeding behaviour was associated with fewer family members and parents or caregivers with at least an undergraduate degree.

La pandemia COVID-19 ha provocado cambios en los estilos de vida, principalmente en los hábitos y conductas alimentarias saludables. Por lo tanto, nuestro objetivo fue evaluar la asociación de los hábitos alimentarios, conductas alimentarias familiares, estilos de vida y percepción del estado nutricional con el riesgo de sobrepeso y obesidad en niños y adolescentes durante la pandemia por COVID-19. Se realizó un estudio transversal, con una muestra n= 661 niños y adolescentes, mediante un cuestionario de autoinforme en línea realizado durante el confinamiento por COVID-19. Se observó 37,5% de malnutrición por exceso. Los estilos de vida como dormir las horas recomendadas según edad y tener conductas familiares saludables disminuyó en 49,0% (OR= 0,510, p= <0,001) y 10,8% (OR= 0,892, p= 0,01) respectivamente, el riesgo de malnutrición por exceso. La percepción de los padres sobre un aumento de peso durante la pandemia, la distorsión del estado nutricional y el riesgo a la salud del estado nutricional de sus hijos aumentó 4.8 (OR= 4,846, p= <0,001), 8,5 (OR= 8,580, p= <0,001) y 3,8 (OR= 3,826, p= 0,001) veces respectivamente, el riesgo de malnutrición por exceso en niños y adolescentes. En conclusión, el confinamiento por COVID-19 y el cierre de las escuelas podrían haber afectado los estilos de vida. Además, es fundamental el rol de los padres en la percepción del estado nutricional y en las conductas alimentarias familiares, ya que podrían ser un factor predictor del riesgo de sobrepeso y obesidad. Estos hallazgos ameritan investigaciones futuras para diseñar planes y programas para evitar las consecuencias relacionadas al sobrepeso y obesidad.

Background and objective: The global aging population has led to increased noncommunicable diseases, often linked to poor diet and declining muscle strength and mass. This study assessed leucine intake and sarcopenia indicators among 181 adults aged 60–80 in Santiago, Chile, participating in the Program for Complementary Food in Older People (PACAM), with 80% being women. Methods: Sarcopenia was evaluated through muscle strength and mass using the EWGSOP2 criteria for its identification. Results: 78.45% of participants did not meet the recommended leucine intake of 3 g per day and sarcopenia was identified in 17.13% of them. The skeletal muscle index was 48.07%, and hand grip strength was 26.52%, with men showing significantly higher grip strength (48.60% vs. 28.80%, p = 0.00). Inadequate leucine intake was more common in those aged 60–75 (85.9%) than those over 75 (p = 0.03). No significant differences in BMI, grip strength, or muscle mass were found between those with adequate and inadequate leucine intake, and PACAM food consumption did not significantly affect these parameters. A sub-analysis showed significant differences in grip strength among powdered dairy drink consumers (35.20% vs. 17.80%, p = 0.01). Conclusions: Chilean elderly participating in PACAM present a high prevalence of sarcopenia and leucine deficiency among with no notable benefits from PACAM foods intake. Despite the limitations of the local body composition assessment method, this research addresses a critical public health issue in Chile. Future studies should evaluate physical performance and focus on leucine supplementation to clarify its effects on sarcopenia.

BACKGROUND: Noninvasive ventilation (NIV) has proven to be useful in the management of children with acute respiratory failure as a result of acute lower respiratory infection. Despite this, evidence addressing the initiation and/or discontinuation criteria of NIV in children remains limited. The objective of this study was to evaluate the usefulness and clinical impact of an NIV protocol in hospitalized children with acute respiratory failure because of acute lower respiratory infection. METHODS: A randomized controlled clinical trial was carried out among subjects admitted during the winter season at Hospital Josefina Martinez between May and October of 2013. Inclusion criteria were age 3 months to 2 y, diagnosis of acute lower respiratory infection and requiring NIV according to a Modified Wood Scale score of ≥ 4 points. Subjects were randomized to NIV management according to medical criteria (control group) or to protocolized management of NIV (protocol group). Hours of NIV, hospital stay, and supplemental oxygen use after discontinuation of NIV, severity changes after NIV initiation, respiratory symptoms, and proportion of intubations were considered as events of interest. RESULTS: A total of 23 subjects were analyzed in the control group and 24 were analyzed in the protocol group. Hours of hospital stay, NIV, and supplemental oxygen post-NIV were not significantly different between groups ( P = .70, .69, and .68, respectively). There were also no differences in intubation rate (3 of 29 for the control group and 2 of 31 for the protocol group). For the total sample there was a statistically significant decrease in the Modified Wood Scale score after 1 h of NIV ( P < .001). A similar result was observed when performing a stratified intragroup analysis. CONCLUSIONS: We observed that the implementation of an NIV management protocol that integrates initiation and discontinuation criteria for NIV is feasible. However, its use showed no advantages over a non-protocolized strategy.

Conocida es la influencia de la fibra dietaria sobre los efectos mecánicos a nivel gastrointestinal, la composición y modulación de la microbiota intestinal y su función en la actividad metabólica y nutricional en adultos. En niños y adolescentes estos efectos son menos conocidos, generando interesantes áreas de investigación y desarrollo científico que nos puedan entregar mayor conocimiento de sus repercusiones a nivel fisiológicos y fisiopatológicos. Esta revisión tiene como objetivo entregar información actualizada sobre las diferentes clasificaciones de fibra, sus principales funciones digestivas y metabólicas, así como las recomendaciones de ingesta diaria en pediatría.
