Food Insecurity and Micronutrient Deficiency in Adults: A Systematic Review and Meta-Analysis.

Food insecurity is a public health problem as it affects a wide array of individuals in the population. It can be characterized by food deprivation, lack of essential nutrition, lack of dietary education, lack of adequate storage conditions, poor absorption, and poor overall nutrition. The relationship between food insecurity and micronutrient deficiency requires more effort to deepen and discuss the relationship. This systematic review aimed to evaluate the association between food insecurity and micronutrient deficiency in adults. The research was conducted according to PRISMA using the Medline/Pubmed, Lilacs/BVS, Embase, Web of Science, and Cinahl databases. Studies carried out with male and female adults were included, which investigated the correlation or association between food insecurity and the nutritional status of micronutrients. There were no publication year, country, or language restrictions. A total of 1148 articles were found, and 18 of these were included, carried out mainly on the American continent and with women. The most evaluated micronutrients were iron and vitamin A. Food insecurity was associated with nutrient deficiency in 89% (n = 16) of the studies. As a result of the meta-analysis, it was observed that there is a greater chance of anemia and low levels of ferritin among food insecure individuals. It is concluded that food insecurity is associated with micronutrient deficiency. Understanding these problems allows the creation of public policies capable of contributing to changes. Protocol registration: This review was registered on the PROSPERO-International Prospective Register of Systematic Reviews database-CRD42021257443.

Predictive capacity and cut-off points of adiposity indices for body fat prediction according to adolescent periods.

Overweight is increasing in the adolescent population and became a public health problem in the world. This study aimed to identify the body adiposity indices (BAI) with the best capacity to predict excess fat tissue and propose cut-off points for them, according to sex and adolescence period. This is a cross-sectional study. We calculated BMI, conicity index (CI), BAI, body roundness index (BRI), waist:height ratio (WtHR) and waist:hip ratio. Predictive capacity and cut-off points of adiposity indices were established by ROC (receiver operating characteristic) curves. We determined AUC-ROC and CI, stratified by sex and adolescence period. The best index to identify excess body fat in 10-13-year-old female adolescents was the WtHR (AUC = 0·92), like the BAI in girls aged from 14 to 16 years old (AUC = 0·87) and 17 to 19 years old (AUC = 0·80). In male adolescents aged from 10 to 13 years old and 14 to 16 years old, the best index was the WtHR (AUC = 0·93 and AUC = 0·8, respectively), like the BAI in boys aged from 17 to 19 years old (AUC = 0·95). The use of indices with specific cut-off points for each period of adolescence and according to sex is important for the reliable diagnosis of excess body fat. It is advisable to use indices together to obtain a more accurate assessment. Thus, the WtHR and BAI are reproducible and reliable, with high sensitivity and specificity values, and can be used together with the BMI.

[Body image of female adolescents and its association with body composition and sedentary behavior]. / Imagem corporal de adolescentes do sexo feminino e sua associação à composição corporal e ao comportamento sedentário.

The scope of this article is to evaluate the body image and its association with body composition, anthropometric indicators and sedentary behavior of female adolescents. It involved a cross-sectional study with female adolescents from Viçosa in the state of Minas Gerais. The body image was assessed by the Body Shape Questionnaire (BSQ) and by the Silhouette Scale. The body fat percentage (BFP) and other anthropometric parameters were measured. The sedentary behavior (SB) was evaluated by the sum of screen time (ST) and cellular time (CT). The sample consisted of 274 adolescents, the majority having an adequate BMI (81.6%), however, 53.9% had elevated BFP. More than half of the adolescents had elevated SB, 68.2% with ST and 54.7% with CT above 2h. Body dissatisfaction was expressed as 45.7% by BSQ and 50.2% wished for a silhouette different than the current silhouette. The waist circumference (WC) (OR = 11.94, CI = 2.744 - 51.728) and waist-to-height ratio (WHR) (OR = 10.535, CI = 3.109 - 35.698) were the measurements most associated with body dissatisfaction. All body composition measurements were significantly associated with body dissatisfaction, and the WC and WHR the most conditioning factors with dissatisfaction. The SB was elevated; however, it was not associated with a negative assessment of body image.

O objetivo deste artigo é avaliar a imagem corporal e sua associação à composição corporal, indicadores antropométricos e comportamento sedentário de adolescentes do sexo feminino. Estudo transversal com adolescentes do sexo feminino de Viçosa, MG. A imagem corporal foi avaliada por meio do Body Shape Questionnaire (BSQ) e pela Escala de Silhuetas. O percentual de gordura (%GC) e outros parâmetros antropométricos foram aferidos. O comportamento sedentário (CS) foi avaliado a partir da soma do tempo de tela (TT) e do tempo de celular (TC). A amostra foi composta por 274 adolescentes, a maioria com IMC adequado (81,6%), porém, 53,9% apresentaram o % GC elevado. Mais da metade das adolescentes apresentaram o CS elevado, 68,2% com o TT e 54,7% com o TC acima de 2h. A insatisfação corporal manifestou-se em 45,7%, e 50,2% desejaram uma silhueta diferente da atual. O perímetro da cintura (PC) (OR = 11,94, IC = 2,744 ­ 51,728) e a relação cintura-estatura (RCE) (OR = 10,535, IC = 3,109 ­ 35,698) foram as medidas mais associadas à insatisfação corporal. Todas as medidas de composição corporal apresentaram associação significativa com a insatisfação corporal, sendo o PC e o RCE os fatores mais condicionantes. O CS mostrou-se elevado, no entanto, não se associou com a avaliação negativa da imagem corporal.
