Abbreviated version of the maternal-fetal attachment scale: evidence of validity and reliability

The Maternal-Fetal Attachment Scale has been widely applied in research on the subject. There are no known studies that have validated a shortened version of this instrument in Brazil. This study aimed to propose a shortened version of the Maternal-Fetal Attachment Scale and examine its evidence of validity and reliability. This methodological study was carried out in the Primary Health Care of Montes Claros, Minas Gerais - Brazil. A sample of 937 pregnant women was evaluated. Construct validity and reliability were measured. A trifactor version with 15 items was obtained, which presented satisfactory adjustment indexes. Convergent and discriminant validities were close to the recommended ones. The scale differentiated attachment scores according to different sample characteristics. Internal consistency (Cronbach’s α = 0.878) and composite reliability (> 0.70) were appropriate. The abbreviated Brazilian version of the Maternal-Fetal Attachment Scale presented satisfactory psychometric attributes for application to pregnant women in Primary Health Care.A Escala de Apego Materno-Fetal tem sido amplamente aplicada em pesquisas sobre a temática.

The association among the consumption of ultra-processed food and body image, nutritional status and physical activity of pregnant women at the primary health care

Abstract Objectives: to analyze the consumption of ultra-processed food and its association with body image, physical activity, nutritional status and self-assessment on food of pregnant women enrolled in the Primary Health Care. Methods: this is a cross-sectional study carried out with pregnant women enrolled in the Family Health Strategy in the city of Montes Claros, Minas Gerais. Data were collected through a questionnaire. The dependent variable was the consumption of ultra-processed food, and the independent ones addressed body appearance, physical activity, nutritional status, self-assessment on food and food consumption. Descriptive analysis was carried out and for association of analysis, the linear regression model was used with crude and adjusted associations. Results: 1,185 pregnant women participated in the study. Caloric intake from ultra-processed food represented 32.0% of these women’s daily diet. There was an association between consumption of ultra-processed food and physical activity (β=-0.08; p<0.01), pre-gestional nutritional status (β=-0,12; p<0.01) and body image (β =0.08; p=0.01). Conclusion: the pregnant women presented high consumption of ultra-processed food. Having a negative body image, the lowest level of physical activity, and high pre-gestational nutritional status are conditions that influenced the consumption of these food
