Nutrition Knowledge, Dietary Habits, and Food Labels Use—A Representative Cross-Sectional Survey among Adults in Poland

Abstract

An unhealthy diet is an important risk factor for disability and premature death. This study aimed to assess nutrition knowledge, dietary habits, and food label use among adults in Poland as well as to identify factors associated with diet-related behaviors. A cross-sectional survey was carried out in July 2020 on a non-probability quota-based sample of 1070 adult citizens of Poland. The most common sources of nutrition knowledge were news websites (41.8%) or family/friends (32.4%). Over one-quarter of adults in Poland were on a diet (28.7%). Over one-tenth of respondents (11.9%) consumed less than three meals per day. Half of the respondents (50.3%) declared that they use food labels when shopping, and 15.4% checked the nutrition information on restaurant menus. Female gender (OR:1.70; 95%CI:1.26–2.29; p < 0.001), presence of chronic diseases (OR:1.83; 95%CI:1.37–2.44; p < 0.001), regular physical activity (p < 0.001), and being a non-smoker (OR:1.45; 95%CI:1.02–2.06; p = 0.04) were significantly associated with higher odds of being on a diet. Females (OR:1.63; 95%CI:1.24–2.15; p < 0.001), respondents with higher education (OR:1.53; 95%CI:1.17–2.01; p = 0.002), those who had never been married (OR:1.49; 95%CI:1.07–2.07; p = 0.02), respondents with chronic diseases (OR:1.73; 95%CI:1.30–2.31; p < 0.001), those with regular physical activity (p < 0.05), as well as non-smokers (OR:1.42; 95%CI:1.04–1.95; p = 0.03) had higher odds of checking the food labels. This study showed a significant gap in nutrition knowledge among adults in Poland.

Healthy Diet-Related Knowledge, Attitude, and Practice (KAP) and Related Socio-Demographic Characteristics among Middle-Aged and Older Adults: A Cross-Sectional Survey in Southwest China

“…Different genders of the study participants showed differences in scores for healthy diet knowledge and healthy diet practice, with females scoring higher than males in both aspects (refer to Table 2 ); this finding was in line with the results from other research [ 38 ]. This finding may have resulted from women being assigned additional responsibilities for cooking and diet decisions in society.…”

Index of cardiometabolic risk based on waist circumference (WHT.5R) and metabolic profile in Polish sedentary male and female students

“…Furthermore, college students, who were mostly male, are considered a population with high-risk behaviours including unhealthy dietary habits, alcohol drinking, and low physical activity, which adversely affect metabolic risk including insulin sensitivity and lipid profile [30,31]. Furthermore, adverse effects of dietary habits on metabolic risk are especially true in the Polish population consuming a diet high in saturated fat and sugar, with low consumption of polyunsaturated fat and micronutrients [32,33]. Therefore, it cannot be excluded that the present data reflect the effect of ectopic fat depots but also the specific diet and lifestyle of students on metabolic risk.…”
