Introduction

Adequate nutrition determines a toddler’s (aged 1-3 years) normal physiological development. Achieving a normal body mass and height reduces the risk of diet-related diseases, such as: hypertension, a disrupted carbohydrate and lipid metabolism (so-called metabolic syndrome), type II diabetes, overweight, and obesity [1-7]. Due to abnormal nutritional behaviours and a lack of physical exercise, the global increases observed in overweight and obesity constitute one of the most important health issues facing the world. Epidemiological studies have shown that the rates of child and adolescent overweight have doubled over the last 25 years, whereas those for obesity have tripled [8]. An excessive body mass has been observed in Europe in around 20% of children, of whom 5% were obese [9-11]. In Poland, the corresponding rates are 15% for those overweight, of whom 2% are obese [12, 13]. During the first 1-3 years of life, the development of children’s psychomotor abilities is most intensive, and thus their diets should be adequately balanced in terms of calories and nutrients. Foodstuffs introduced into children’s diets by their parents/legal guardians, along with their consumption rates, do not always comply with EU recommendations nor those prepared domestically in Poland by the Institute of Food and Nutrition (IFN) [14-17]. Moreover, children do not, as a whole, uniformly reject newly introduced foodstuffs just because they taste different when compared to ones they are already familiar with. It is well recognised that frequently eaten foodstuffs at such an early age have an influence on how tastes develop and on later eating choices [18, 19]. The dietary behaviour of parents/legal guardians, as well as their knowledge base of adequate nutrition, also significantly affect their children’s nutrition. Inappropriate dietary habits already acquired in childhood create disadvantageous nutritional behaviours that are often exacerbated whenever there is poverty and/or poor living conditions at home.

Aim of the study

To assess nutrition in toddlers aged 13-36 months, who live in the Greater Poland region of Poland, according to:
nutritional status and currently binding nutritional recommendations,
selected anthropometric indicators (of body mass and height) according to World Health Organization (WHO) standards.

Material and methods

A pilot survey-study by questionnaire was first conducted in March 2019 on 30 mothers and their 13-36-month-old children who were attending the “Profamilia” Paediatric Health Centre in Kozielgowy Town in the Greater Poland (Wielkopolska) region of Poland. Subsequently, the main study used an amended form of the survey-questionnaire conducted in the same year from May to July, also at the same health centre, on a sample of 520 randomly selected children aged 1-3 years, together with their parents/legal guardians. There were 332 girls (64%) and 188 boys (36%), having an overall average age of 23.3 months. The proportions of subjects living in urban and rural areas were comparable: respectively, 52% and 48%. There were 54% of parents with higher education obtained either at university or technical college, whereas 33% had upper-level secondary education, and 13% had lower-level secondary education or vocational education (Table 1). For the study, a questionnaire developed in-house was used together with a diet-diary, which patients filled in daily with details of the types of foodstuffs consumed and their frequency. This was done during two days of a particular week and on one bank holiday (feast day). The questionnaire was completed by the parents/legal guardians in the presence of a study surveyor and consisted of three parts. Part one dealt with the socio-environmental conditions of family life. Part two was concerned with the anthropometric parameters of the child, such as body mass and height, which were obtained from the child’s medical record book (Health Card), along with details of illnesses suffered and the type and duration of the actual childbirth. Part 3 was about the child’s nutrition and their food preferences. The responses thus obtained served to establish children’s nutritional behaviour and how the parents fed their children. Before starting the study, all participants were notified by the study surveyor that their inputs were taken as being both voluntary and anonymous. Statistical analyses were performed using the IBM-SPSS Statistics 23 package. The number sizes (mean and standard deviations) and proportions (rates) of each variable were thereby obtained. The significance of differences and any associations in nutritional behaviour between variables were assessed by summary statistics, the Kolmogorov-Smirnoff test, Spearman’s Rank Correlation, the c2 test, and the Fisher exact test; all taking p < 0.05 as being significant.

Results

Seventy eight percent of the children were breast fed. A worrying feature, however, was that none had been exclusively breast fed during the first six months. Nutritional guidelines prepared by the IFN state that children should optimally eat 4-5 meals daily, taking into account the types of foodstuffs in their diet. Also considered are the daily frequency of foodstuff consumption as well as their qualitative and quantitative content [14]. Systematically eating five meals daily results in the body getting used to receiving an optimal intake of calories and nutrients to ensure appropriate metabolism. Our study showed that 78% of subjects ate 4-5 meals daily, whilst one in five ate six or more daily meals; the latter running the risk of becoming overweight (Fig. 1). Parents/legal guardians declared that they mainly prepared one-dish meals (79%) as opposed to two-dish meals (21%). Nevertheless, one in five parents took their children’s eating preferences and age into account when preparing meals; in fact, over half did so whenever time permitted (Fig. 2). We have also shown that parents widened the scope of their children’s diets according to the stages of their development – within the age range of 4-7 months (mean 4.23 months), children were supplementarily fed with the following foodstuffs: fermented dairy products, eggs, poultry, red meat, cold meats, fish, fresh fruit, vegetables, and cereals. Two daily portions of milk or dairy products are recommended, where milk can be partly replaced by one portion of fermented dairy products, such as yogurt, kefir, and cream/homogenised cheeses [14]. Our results demonstrated that the most frequently consumed dairy products were milk (39%), natural yogurt (12%), cheese (15%), and cream cheese (20%). Only 1%, however, ate buttermilk or kefir. Eggs are a good dietary source of protein and fat in children. They also contain many desirable vitamins (fat soluble: A, D, E, and K), minerals and lutein, which is responsible for normal eye function. A weekly dietary intake of 3-4 eggs is recommended (i.e. amounting to half an egg daily) [14]. Our study showed that 40% of the children ate one egg daily. Children’s diets should not lack meat nor cold meats, so as to ensure the body’s requirement for complete (whole) protein. Almost half the parents gave their children meat from 4-5 times weekly; one in five did so daily. It should, however, be noted that 6% ate no meat at all, presumably because they were on vegetarian diets. Parents prepared the following meats most frequently: poultry (94%), pork (68%), beef (44%), and rabbit (25%). Certain principles should be generally adopted in consuming these foodstuffs. Beef and pork should be replaced by skinless poultry and fish (especially sea fish). Fish should be baked or boiled and served to children 1-2 times weekly [14]. Our results showed that 63% of children ate fish once weekly, but only 14% did so 2-3 times weekly. Parents never giving their children fish comprised 14%, which is a source of unsaturated omega-3 fatty acids. One of the most common faults observed in children’s diets is in the eating of sufficient vegetables. These should be eaten more frequently than fruit (in a recommended 3/4 to 1/4 ratio), because the latter contains more simple sugars and are more calorific [14]. Our study showed that this proportion was not adhered to; more fruit was eaten (84%) than vegetables (76%). Children’s diets were not also lacking in sweet snacks (confectionery). Sweets were eaten daily by 12%, 3-4 times weekly by 42%, and 2-3 times weekly by 36%. Such outcomes could lead to nutritional deficiencies and overweight. Another important foodstuff grouping in children’s diets are cereals, which deliver complex carbohydrates, fibre, group B vitamins, and minerals. Furthermore, combining cereals with milk products improves the dietary intake of vegetable protein [14]. Diverse breads/cereals are recommended in children’ diets: wholegrain, white and brown bread, different types of coarse or fine groats, and porridge oats. We showed that 83% of children ate all kinds of cereal products, 13% ate wholemeal ones, and 4% ate those that were gluten-free (Table 2). The different types of fats and oils that parents used for making sandwiches or cooking with were also determined. Most children ate buttered bread-sandwiches (72%), whilst parents mainly used vegetable oils for cooking (56%). Oil was used by 10% on sandwiches, whilst 15% of parents fried food without any oil/fat (Fig. 3). A vital dietary component is the daily fluid intake. Drinking around 1300 mL of fluid daily is required for children aged 1-3 years [14]. Our findings show that 8% of children drank more than 1.5 L daily, 58% drank 1-1.5 L daily, but 35% drank less than 1 L daily. Parents mainly gave water as the fluid (72%) but also sweetened drinks like flavoured water (34%), sugared tea (68%), juices (54%), and soda-pop (12%). Anthropometric measurements were used to assess children’s nutritional status (body mass and height), which were provided by the parents/legal guardians from medical cards. If current data were unavailable, then such measurements were taken at the family’s health centre. The BMIs were thereby determined (kg/m2) and referenced to centile charts of body mass and height. The WHO has defined the following BMI ranges: < 5th centile as underweight, ≥ 5th centile < 85th centile as normal body mass/weight, ≥ 85th centile < 95th centile as overweight, and ≥ 95th centile as obese [20]. We found that 71% of our subjects had normal BMI, whereas 15% were underweight. It should, however, be noted that we found higher rates of obesity (8%) than overweight (5%). There were also higher rates of normal BMI for those living in rural areas (countryside) than for city dwellers (Table 3).

Discussion

Adequate nutrition after childbirth and during the first years of life are among the most vital factors that determine optimal development, both somatic and mental. Irreversible changes to metabolism and endocrine function are caused by adverse environmental factors, like deficient or excessive dietary intakes, which can be experienced during the most crucial times in human development. This model is defined as programmed nutrition focused on child-bearing and infant age [21] – one of the related factors being breast feeding. The European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) recommends that children should be exclusively fed on breast milk up to the sixth month [17, 22]. Breast feeding should, however, continue afterwards with the cotemporaneous introduction of supplementary feeding. The correct amount and composition of breast milk ensures that the required calories and nutrients are supplied during the first six months of life. A mother’s breast milk given in sufficient amounts by an adequately nourished mother fully satisfies the infant’s demand for calories and all nutrients, which allows normal development in the first months of life [23-26]. Our study shows that 78% of mothers breast fed their offspring; however, it is of concern that none of the infants had exclusively received only their mother’s breast milk. A study by the Mother and Child Institute showed that only 56% of children were breast fed during the first half year of life, of whom only one in five were exclusively breast fed [27]. The next dietary stage for infants is to broaden the scope. Foodstuffs other than milk or modified milk should be introduced from six months onwards. This is primarily because milk by itself becomes insufficient to meet the child’s calorific demands, and the digestive and excretory systems at this time are ready to process other types of food [14]. Nevertheless, the parents’ level of knowledge about broadening the scope of an infant’s diet at this time does not concur with current standards. Our results demonstrate that parents broadened their children’s diets between four to six months. This usually happened early; other foods had been introduced a mean of 4.23 months. Brazilian studies conducted on children aged 1-3 years found that the age when infants were given supplementary food was 5.3 months [28]. A USA cohort study showed that 40% of children received food other than breast milk at four months [29]. Likewise, a UK study found this to be the case also after a mean of four months [30]. It appears that our subjects received adequate nutrition in terms of the number of daily meals and how they were prepared (one or two dish meals). We showed that 78% of subjects who were not breast feeding ate 4-5 meals daily. Tailoring meals the suit the child’s preferences was only possible when time allowed the parents/legal guardians to do so. A Poland-wide study found that children of the same age ate at least five meals daily [27]. Micro- and macro-nutrients constitute a vital part of an adequate diet for children. Our findings show that there are dietary deficiencies in the consumption of milk, dairy products, fish, and foods rich in unsaturated fatty acids. Milk and its products are an ideal source of calcium, protein, vitamins (B11, B2, B6 and B12), folic acid, vitamin A, and magnesium. Calcium is readily absorbed from milk products, and the recommended daily milk intake covers 60% of the calcium requirement [14]. The presented study shows that 39% subjects aged over 13 months drank milk daily. A Poland-wide study also showed such low levels of milk consumption when compared to standard models of adequate nutrition [27]. A child’s diet should be rich in both animal fat (i.e. butter) and in vegetable and olive oils. We found that parents mostly served buttered sandwiches, whilst only 5% used margarine. Over half used vegetable oil for frying. Only 15% fried without any fat or oil. A PITNUTS study from 2016 showed that children consume 40% more trans-fats than the recommended intake of 11.1 g/day [27]. The low dietary amounts found of long-chain polyunsaturated fatty acids and vitamin D was because children ate fish rarely, and 22% never ate fish. Meat and its products replaced fish in the diet, which has also been confirmed in USA studies [31]. A complete daily diet for children should contain fruit and vegetables. These possess antioxidant properties, inhibit cell proliferation, regulate hormone action, and stimulate the immune system. Furthermore, every portion of fruit and vegetables delivers a wide range of bioactive compounds like carotenoids, vitamins C and E, folic acid, selenium, flavonoids, and fibre [14]. Children’s diets are rich in mainly simple sugars due to the fact that fruits are tasty and are keenly eaten by children, and thus they are more frequently given by parents. A study by Harton et al. on pre-school children showed a two-fold higher rate of fruit consumption compared to vegetables [32]. Similar findings were observed in the USA on 2-3-year-olds, where 70% ate vegetables at least once daily, whereas 73% ate fruit as a separate foodstuff [33]. Similar outcomes to ours were observed in an Australian study, in which the majority of child subjects consumed recommended foodstuffs such as cereal products, meat or poultry, fruit, and vegetables. Nonetheless, there were increasing rates of children consuming energy-dense foodstuffs, particularly for those aged 9-18 months. They included sugary drinks and sweet snacks [34]. We found that 12% ate sweets daily, 42% did so 3-4 times weekly, and 36% 2-3 times weekly. Fox et al. indicated that 85% of children aged 2-3 years drank sugary drinks and ate sweet desserts or snacks [33]. Other studies on children aged below two years have likewise found high consumption of these foodstuffs, which are poor in nutrients but high in calories [27, 31, 35, 36]. Maintaining an appropriate water-mineral balance is especially important in young children. Clean water intended for consumption by infants and toddlers should be naturally free of chemicals and micro-organisms, but it should have the necessary complement of minerals. Source and natural water are recommended for infants, as well as waters with low sodium and mineral content [14, 37]. We found grave shortcomings in our results on children’s water intake. Every third child drank less than 1 L of fluid daily. Moreover, parents declared that their children drank sugary drinks such as sugared tea, juices, and soda-pop. A study by Budnee et al. showed that 54% of one-year-olds drank sugary soda-pops daily [38]. Miles and Siege-Riz found that USA children aged 12-33 months drank sugary soda-pops [39]. We demonstrated abnormal body mass and height according to age. The most numerous group (71%), however, had normal body mass conforming to accepted centile references. Underweight was seen in 15% of cases, whilst overweight or obesity in 13%. Likewise, the aforementioned PINUTS study showed that 68% of subjects possessed a normal body mass, but they found disturbingly high rates of overweight and obesity: respectively, 25% and 4% [27]. Our study, however, observed a significantly higher proportion of children with normal BMIs than a study by Weker et al. (at only 46%), although similar outcomes were seen in the numbers of overweight, at 13%. However, the combined overweight and obesity rates were 28% [40]. The literature shows that the rapid rise in body mass at infancy affects the development of overweight and obesity in childhood [41]. All this demonstrates the need to check with recommendations that concern child nutrition and to continue educating parent/legal guardians about nutritional matters, in order to prevent obesity. Parents and legal guardians shape their child’s lifestyle, both in quantitative and qualitative aspects of food. The literature indicates that children brought up in an authoritative manner at home usually eat more healthily, are more physically active, and have lower BMI compared to those whose upbringing is liberal and indulgent [42, 43].

Conclusions

In our own research it was shown that 78% of women breastfed their children. It is worrying that none of the examined children received mother’s food until six months. In our own research in children’s diets we see insufficient consumption of milk and dairy products, and fish – too low a share of products rich in unsaturated fatty acids. In the studied population, excessive consumption of sweets, insufficient consumption of vegetables and fruit, as well as insufficient fluid supply for age and body weight were found. In the studied population, 6% of children did not consume meat at all. The effect of improper diet of the studied population is malnutrition in 15% of children and overweight or obesity in 14% of children. Facilitating access to a doctor and dietitian, as well as educational programs, can improve the diet of children and reduce the occurrence of diet-related diseases. There is a continuing need to increase the education of carers in expanding the infant’s diet due to nutritional errors that are still occurring and are being reproduced.
