Activity-Inactivity Patterns, Screen Time, and Physical Activity: The Association with Overweight, Central Obesity and Muscle Strength in Polish Teenagers. Report from the ABC of Healthy Eating Study.

Today, the time spent actively is increasingly being replaced by screen-based media, although in some teenagers, a high level of physical activity (PA) and longer time spent in front of a screen (screen time, ST) may coexist as a mixed behavioral pattern. This study aimed to examine the association of the pattern created as activity (low/high ST with high PA) and inactivity patterns (low/high ST with low PA) with overweight, central obesity, and muscle strength in Polish teenagers taking into consideration socioeconomic and demographic factors. Cross-sectional data were collected from elementary school children ( = 1567), aged 11-13 years.

Reproducibility of a Short-Form, Multicomponent Dietary Questionnaire to Assess Food Frequency Consumption, Nutrition Knowledge, and Lifestyle (SF-FFQ4PolishChildren) in Polish Children and Adolescents.

The aim of the study was to assess the reproducibility of a short-form, multicomponent dietary questionnaire (SF-FFQ4PolishChildren) in Polish children and adolescents. The study involved 437 children (6-10 years old) and 630 adolescents (11-15 years old) from rural and urban areas of Poland. The self-administered questionnaire was related to nutrition knowledge, dietary habits, active/sedentary lifestyle, self-reported weight and height, and socioeconomic data.

Assessment of nutritional behaviour of children aged 3-7 from selected kindergartens in Biala Podlaska county.

Background: Children constitute a group that is particularly susceptible to the effects of improper nutrition. The knowledge of parents and guardians about proper nutrition affects their children’s nutritional habits and behaviours. Children develop their patterns of nutritional behaviours on the basis of their observations of nutritional habits of adults, nutrition trends and nutritional education.

Body composition and fatty tissue distribution in women with various menstrual status.

Background: Menopause, also referred to as climacterium, is a period of multiple changes in the structure and functions of a woman organism.

Objective: Determination of differences in body composition and fatty tissue distribution in women from groups discriminated based on their menstrual status.

Material And Methods: The survey covered 312 women aged 38-75 years.

Assessment of nutritional behaviours of children aged 7-12 attending to primary schools in Biala Podlaska, Poland.

Background: Children and youth constitute a group that is particularly prone to the effects of improper diet. In the puberty period, numerous significant lifestyle choices are made, for instance regarding particular nutritional behaviours which may be repeated later in life and may determine the state of health.

Objective: The aim of the study was to assess nutritional behaviours of children aged 7-12 attending to primary schools in Biala Podlaska county (Eastern Region of Poland).

Evaluation of the Usability of Selected Questionnaires Assessing Physical Activity in the Prophylaxis of Cardiovascular Diseases.

Background: The main health problem of the Polish population is posed by cardiovascular diseases (CDVD), coronary artery disease (CAD) in particular. Respectively higher physical activity linked with energy expenditure of at least 1000 kcal/week may significantly reduce the risk of CAD development. The protective effect of exercise applies not only to persons from high-risk groups and with diagnosed chronic diseases that increase the risk of the incidence of atherosclerosis and its complications, but also to healthy individuals.

Body fat-based weight norms for children and youths.

Introduction: The issue of establishing reference values, especially of those pertaining to somatic features, is of importance for an assessment of normal growth. It was assumed that norms ought to reflect not the actually existing status but the recommended one. Thus, weight-height relations, including body mass index (BMI), ought to be established for that fraction of the general population, in which body fat content is within physiologically acceptable limits.

[Nutritional patterns versus BMI values in rural adolescents].

The study was aimed at determining relationships between the daily intake of food rations, energy consumption and energy balance in adolescents differing in the BMI value. The experiment covered 280 girls and 305 boys aged 10-15 years. Somatic traits were evaluated based on measurements of body height, body mass and thickness of skinfolds (arm triceps, subscapular, abdominal), whereas energy consumption was assayed by means of a triple 24-h dietary recall interview carried out prior to examinations.

The effect of socio-economic and demographic determinants on the pattern of consumption of rural adolescents.

The aim of this study was to determine the effect of selected socio-economic and demographic determinants (the number of children in the family, father's education, standard of living, sex and age) on the pattern of consumption in adolescents occupying rural areas of the central-eastern Poland. The study included 564 boys and 548 girls 10-15-years-old. Data on the socio-economic status and dietary habits were collected by means of a diagnostic survey.

[Calcium and phosphorous content in daily rations of adolescents from Biała Podlaska District].

The aim of the study was to assess the Ca and P intake and Ca:P ratio in daily rations of boys and girls aged 10-15 years. Calcium intake amounted to 51% and 65% of safe intake level of RDA for 10-12 and 13-15 years old boys and 43% and 44% for girls, respectively. Phosphorus intake exceeded the RDA and amounted to 141-165% for boys and 122-133% for girls.
