RESUMO
OBJECTIVES: To study prevalence of infection in essential workers of Madrid City Council by occupation, related characteristics, use of protective devices, risk perception, and main concerns about COVID-19 during lockdown. METHODS: A total of 30 231 workers were PCR tested for SARS-CoV-2 infection. Information was collected on COVID-19-related symptoms, risk factors, preventive equipment, and risk perception. The crude prevalence was calculated for infection, use of protective devices, perceived risk and main concerns. Additionally, adjusted prevalence and prevalence ratios (PR) were estimated for these variables using logistic regression models with age, gender, occupation, epidemiological week and laboratory as confounding factors. RESULTS: Overall prevalence of infection was 3.2% (95% CI 3.0% to 3.4%), being higher among policemen (4.4%) and bus drivers (4.2%), but lower among emergency healthcare personnel, firefighters, food market workers and burial services (<2%). Lower excess risk was observed in workers reporting occupational contact with COVID-19 cases only (PR=1.42; 95% CI 1.18 to 1.71) compared with household exposure only (PR=2.75; 95% CI 2.32 to 3.25). Infection was more frequent in symptomatic workers (PR=1.28; 95% CI 1.11 to 1.48), although 42% of detected infections were asymptomatic. Use of facial masks (78.7%) and disinfectants (86.3%) was common and associated with lower infection prevalence (PRmasks=0.68; 95% CI 0.58 to 0.79; PRdisinfectants=0.75; 95% CI 0.61 to 0.91). Over 50% of workers felt being at high risk of infection and worried about infecting others, yet only 2% considered quitting their work. CONCLUSIONS: This surveillance system allowed for detecting and isolating SARS-CoV-2 cases among essential workers, identifying characteristics related to infection and use of protective devices, and revealing specific needs for work-safety information and psychological support.

BACKGROUND: [corrected] In order to ascertain the food intake and nutritional situation of the children of the Community of Madrid, on which no updated information was available, the Institute of Public Health conducted the 2001/2001 Children's Nutrition Survey of the Community of Madrid (CNSCM). This study offers an analysis of the CNSCM that describes and evaluates the food, energy and nutrient intake of this segment of the population. METHODS: Cross-sectional survey on a representative sample of children aged 5-12 years from the Community of Madrid. Diet-related information was collected in 2001 and 2002 by means of two 24-hour recalls. Total daily food, energy and nutrient intake were studied. The analysis included only the 1852 children who had completed both 24-h recalls (90.8% of all interviews). RESULTS: The average daily food intake is 1460.7 grams/person/day. Except for dairy products, eggs and oils, intake from the basic food groups is inadequate, and is particularly low for fresh fruits, green leafy vegetables and garden vegetables in general. The resulting average energy and nutrition intake is 1905.9 kcal/person/day; 43.6% carbohydrates, 17.4% proteins, 39.0% fats (13.3% saturated fats, 16.8% monosaturated fats, 5.0% polyunsaturated fats); 363.8 mg cholegterol, 13.6 g of fiber and lower than recommended intakes of zinc, folic acid, vitamins D and E (both sexes) and iron and vitamin B6 (girls). CONCLUSIONS: The diet of the children of the Community of Madrid shows a number of imbalances that should be improved: inadequate intake from basic food groups; excess of proteins, saturated fats and cholesterol; and a deficit of carbohydrates, fiber and certain micronutrients.
