Analysis of physical activity in preschool children from Piła. Part 1. Ordinary and additional physical activity and favourite ways of spending leisure time**
Food and Nutrition Department of the Eugeniusz Piasecki University School of Physical Education in Poznań, Poland
Head of the Department: prof. dr hab. Wojciech Chalcarz
Summary
Aim. The aim of this study was to analyse ordinary and additional physical activity in preschool children from Piła and to investigate their favourite ways of spending leisure time.
Material and methods. Parents of 165 preschoolers from Piła filled in questionnaires on general information about their children and their families, the children’s ordinary and additional physical activity, and their favourite ways of spending leisure time. Statistical analysis was performed by the IBM SPSS Statistics 21 computer programme. The studied population was divided according to gender.
Results. Gender had statistically significant influence on parents’ answers to the questions about familial osteoporosis and about their opinion on their children’s body weight, as well as the percentages of children who preferred playing with a ball and rollerblading/roller skating during sunny weather and drawing/painting, playing with building blocks, playing computer games, playing with dolls and playing with toy cars during rainy weather.
Conclusions. In comparison to the previously studied preschool children from other regions of Poland, the studied preschoolers from Piła were characterised by reduced ordinary and additional physical activity. To reverse these unfavourable changes, it is necessary to educate preschoolers’ parents, preschool staff and local authorities about the possibilities of increasing the children’s physical activity and reducing their time spent in a passive way. Children, irrespective of gender, should be encouraged to various kinds of physical activity.
INTRODUCTION
Although it has been as many as 33 years since the first Polish publication which emphasised the importance of physical activity in maintaining preschool children’s health (1), this problem not only remains, but has become one of the main issues in the area of public health. Both our studies on preschool children (2-8) and studies carried out in other countries (9-13) indicate that preschoolers’ physical activity is decreasing while the prevalence of obesity among children and adolescents is increasing (14-17).
Decreased physical activity in preschool children is one of the cause of their unwillingness to take part in physical education classes when they move to school. This problem was raised in the Polish Supreme Audit Office report published recently (18). Therefore, it is necessary to monitor physical activity in preschool children from various regions of Poland and to undertake intervention programmes as quickly as possible.
AIM
The aim of this study was to analyse ordinary and additional physical activity in preschool children from Piła and to investigate their favourite ways of spending leisure time.
MATERIAL AND METHODS
Parents of 165 preschoolers, including 79 girls and 86 boys aged 3 to 6 years who attended preschools in Piła, were asked to fill in questionnaires on general information about their children and their families, health status of the children and their families, the children’s ordinary and additional physical activity (the way of going to preschool and coming back home, active ways of spending time at preschool and outside preschool, passive ways of spending leisure time outside preschool), as well as the children’s favourite ways of spending leisure time during sunny and rainy weather. The questions included in the questionnaires were used in our previous studies (4-7).
The study was approved by the Bioethics Committee of the Poznan University of Medical Sciences. Parents were informed during a special meeting about the methods of the research and provided written consent to participate. The study was carried out in September/October 2010.
Statistical analysis was performed by the IBM SPSS Statistics 21 computer programme. The studied population was divided according to gender. Quantitative variables were first analysed using the Shapiro-Wilk statistic for testing normality. The level of significance was set at P ≤ 0.05. For all the analysed quantitative variables, means and standard deviations were calculated (x ± sd). To investigate statistically significant differences between subgroups, the unpaired Student’s t test for normally distributed variables and the non-parametric Mann-Whitney U test for skewed variables were used. The level of significance was set at P ≤ 0.05. Qualitative variables were presented in contingency tables. Statistical significance was determined using Pearson’s chi-square test, except for the variables with 2 x 2 tables with an expected frequency of less than five in at least one subgroup for at least one answer. In this case, Yates’ corrected chi-square test or Fisher’s exact test was used. The level of significance was set at P ≤ 0.05.
RESULTS
Characteristics of the studied population
Tables 1 to 3 present, respectively, general information about the studied preschool children from Piła and their families, health status of the studied preschool children and their families, and parents’ opinion on their children’s body weight and health status according to gender. Children’s gender had statistically significant influence on parents’ answers to the questions about familial osteoporosis and about their opinion on their children’s body weight.

DISCUSSION
Characteristics of the studied population
The studied population of preschoolers from Piła comprised the same number of children as the population of children from preschools in Poznań (5), however, the percentage of girls was higher. The populations of children from preschools in Pabianice (2), in the Mazowsze region (6), in Nowy Sącz and the vicinity (4), in Darłowo (7) and from various regions of Poland (3) included a lower number of children. The studied children from Piła were younger than preschoolers from Nowy Sącz and the vicinity (4) and slightly younger than their peers from preschools in Darłowo (7), in Poznań (5) and in the Mazowsze region (6). They also had younger mothers and fathers (5-7).
In comparison to mothers of the previously studied children (4-7), the highest percentage of mothers of the studied preschoolers from Piła had secondary education, whereas the percentage of fathers with secondary education was the same as the percentage of fathers of children from the Mazowsze region (6) and higher than the percentage of fathers of children from Darłowo (7) and Poznań (5). The percentage of parents of the studied preschoolers from Piła who assessed the economic status of the family as very good was the same as the percentage of parents of children from preschools in Darłowo (7) and lower only than the percentage of parents of children from the Mazowsze region (6). The percentage of parents of the studied preschoolers from Piła who assessed the economic status of the family as good was lower only than the percentage of parents of children from Darłowo (7).
In comparison to the previously studied children from preschools in Darłowo (7) and in the Mazowsze region (6), the studied population of preschoolers from Piła was found to comprise the highest percentage of girls who suffered from food allergies and took medicines, and the highest percentage of boys who suffered from other allergies and took medicines. However, the percentage of both girls and boys from Piła who followed special diets due to health problems was the lowest. It is obvious that children who suffer from food allergies should follow elimination diets (19, 20). Meanwhile, among the studied preschoolers not only a very small percentage of children followed a special diet, but also the percentage of parents who assessed their children’s health status as good was very high, similar to the percentage of parents of girls from Darłowo (7) and the percentage of parents of boys from the Mazowsze region (6). It seems that the health care professionals should pay more attention to educate parents on their children’s health. The importance of this issue was highlighted a long time ago (21). The inability to assess adequately the health status of one’s own child is very disconcerting since caring for health and proper development of the children is one of the basic roles of the family (22). Such attitude of the studied children’s parents is difficult to understand and it is not clear whether it is the result of unawareness or irresponsibility. A paediatrician should draw the parents’ attention to the health status of their children.
It is difficult to explain why in the families of the studied preschoolers from Piła, the prevalence of familial hypertension, diabetes and myocardial infarction reported by parents was higher than in the families of children from Darłowo (7) and the Mazowsze region (6) and why the prevalence of familial osteoporosis was lower.
Ordinary and additional physical activity
There were many unfavourable findings on the ordinary and additional physical activity in the studied preschool children from Piła.
Firstly, the percentage of the studied preschoolers who went to preschool on foot was lower than the percentage of children from Poznań (5), Darłowo (7), Nowy Sącz and the vicinity (4) and the Mazowsze region (6), whereas the percentage of the preschoolers who were driven in a car was higher. Similar findings were also reported by Australian researchers (23). It is also the first time in our research (4-7) when we observed such a little increase in the percentage of children who went back home from preschool on foot in comparison to the percentage of children who went to preschool on foot. Usually, the percentage of preschoolers who went home on foot was much higher than the percentage of preschoolers who went to preschool on foot which was probably the result of the fact that the children went back home with their grandparents or siblings who did not have a car. Most probably the observed change is the result of the fact that availability of the car to most of the society has increased over the period when our studies were carried out. This availability is also the reason for the habit of using the car on any occasion. Driving children to preschools and schools in a car will lead to further reduction in children’s physical activity which was shown by the American researchers (24).
Secondly, the percentage of the studied preschoolers from Piła who attended organised physical exercise classes at preschool was much lower than the percentages of girls and boys from preschools in the Mazowsze region (6) and in Darłowo (7). Only the percentage of the studied preschoolers who attended callisthenics for children at preschool was similar to the percentage of children from Darłowo (7) and higher than children from the Mazowsze region (6). Also, the percentage of the studied children from Piła who attended organised physical exercise classes outside preschool was only a little higher than the percentage of children from the Mazowsze region (6) but as many as twice lower than the percentage of children from Poznań (5). Organised physical exercise classes conducted by experienced teachers play an important role in developing children’s motor skills (25). Unfortunately, parents of preschoolers from Piła were most probably unaware of this. They not only did not pay much attention to their children’s attendance to organised physical exercise classes, but also a small percentage of them did physical exercise at home with their children or went for a long walk with their children every day. From the public health point of view, it is of high importance to provide various physical exercise classes to children at preschool which should be obligatory and free of charge for every child. It is also indispensable to spread among preschoolers’ parents and local authorities the knowledge of the role of organised physical exercise classes in motor development of the child. Very helpful tools for this purpose are provided within the programmes of increasing physical activity (26-29).
Thirdly, a very harmful to children’s health was the fact that the percentages of the studied preschoolers from Piła who watched television for two hours, three hours or four hours and more every day were higher than the percentages of their previously studied peers from Darłowo (7), Nowy Sącz and the vicinity (4), the Mazowsze region (6) and Poznań (5). Adverse effects of spending long hours in front of a television include higher risk of obesity due to reduced time of physical activity along with increased time of sitting and consuming unnecessary additional energy from high-energy foodstuffs and beverages, being exposed to commercials of high-energy, unhealthy and not recommended foods, as well as limiting time for sleep (30-33). Moreover, long hours of watching television by the children reduce the direct contact and spending leisure time with siblings, parents and peers, worsens sight, favours faulty posture and inadequate psychomotor development. Early exposure to television viewing is also associated with sedentary behaviours later in primary school (34), as well as in adolescence and adulthood (35). According to the recommendations of Canadian Society for Exercise Physiology, parents should limit screen time of 2- to 4-year-old children to under one hour per day and to a maximum of two hours for 5- to 6-year-old children (36, 37).
Favourite ways of spending leisure time
Similarly to the previous studies (4, 5, 7), the most preferred ways of spending leisure time during sunny weather by the studied preschoolers included riding a bicycle, playing in a playground and going for a walk, however, the percentages of the studied children from Piła who preferred these ways of spending time were higher than among their previously studied peers. These findings indicate that the studied preschoolers were keen on physical activity. However, it depends on their parents whether the children are able to undertake various forms of physical activity. Parents should be encouraged to promote among their children the habit of spending leisure time outdoors from the early childhood because children who spend more time outdoors are more physically active (38).
In the studied preschool children from Piła, some social stereotypical influences were observed reflected in the higher percentage of boys who preferred playing with a ball and higher percentage of girls who preferred rollerblading and going for a walk. This observation is similar to the findings of our previous studies (5-7). This is the result of a common belief that some activities are adequate for the girls while other are adequate for the boys. However, the percentages of the studied girls and boys who preferred riding a bicycle were similar contrary to the previous studies in which higher percentages of boys preferred this kind of activity (5-7). This is highly favourable and it is important to note that children, irrespective of gender, should be encouraged to various kinds of physical activity.
During rainy weather, the studied preschoolers from Piła preferred mainly passive ways of spending leisure time, similarly to their peers from other regions of Poland (5-7) as well as from other countries (39-41). Moreover, similar gender-dependent tendencies were observed, that is only girls preferred playing with dolls and only boys preferred playing with toy cars. Higher percentage of girls compared to boys preferred drawing/painting, whereas higher percentage of boys preferred playing computer games and playing with building blocks. These preferences are most probably caused by cultural influences. Gender differences in physical activities are typical (42, 43) and reflect traditional approach to these activities as gender-dependent. Such an approach is not good for future understanding between men and women, as well as for spending time actively together with the spouse.
CONCLUSIONS
1. In comparison to the previously studied preschool children from other regions of Poland, the studied preschoolers from Piła were characterised by reduced ordinary and additional physical activity which was reflected in the higher percentage of preschoolers driven by car to preschool and back home, allowing the children to spend more time watching television, not going for a long walk every day and not doing physical exercise at home by the parents with the child.
2. To reverse these unfavourable changes, it is necessary to educate preschoolers’ parents, preschool staff and local authorities about the possibilities of increasing the children’s physical activity and reducing their time spent in a passive way.
3. Children, irrespective of gender, should be encouraged to various kinds of physical activity.
