Background
Overweight and obesity in preschool children have increased worldwide and currently affects 40 million children younger than five years of age [
1]. Moreover, obesity in preschool children correlates strongly with increased risk for obesity in adolescence [
2]. This and many other well-documented associated health consequences of obesity [
3] call for preventive interventions in early childhood. In Sweden, representative national data from a survey performed in 2008 showed an overweight prevalence of 17% of children aged seven to nine years, including 3% with obesity [
4]. No representative national data are available in preschool children. However, in two separate studies, one from the north and one from the south of Sweden, from 2007/2008 and 2003–2008, respectively, showed similar prevalence data of overweight and obesity in four-year-old children. Overweight was present in about 15 to 17% and obesity in 3% of the children [
5,
6].
Although childhood obesity is common in both rural and urban areas [
1], reports suggest that it occurs more frequently in children from lower socioeconomic groups [
1,
7]. The World Health Organization (WHO) recommends population-based prevention strategies on multiple levels to counteract the epidemic of childhood obesity [
1]. Primary health care is a key setting for monitoring health in preschool children and preventing childhood obesity.
In Sweden, Child Health Centers (CHC) date back to 1938, when the Swedish Parliament decided to offer regular and free CHC visits to all children from birth to six years of age [
8]. Today, such visits are widely accepted (up to 99.9% between birth and the age of one year) [
9]. CHCs are staffed and run autonomously by specialized full-time nurses who are responsible for general health care in cooperation with part-time physicians, who are responsible for the medical aspects of health care. The national program for CHCs includes growth monitoring, vaccinations, disease screening, counseling on feeding practices, accident prevention and promotion of an active childhood and healthy family lifestyle. Children and their parents see CHC nurses 15 or more times compared to three to five visits to a physician. The interaction between nurses and parents on issues related to children’s growth and healthy lifestyle crucially affect impact and outcome.
This study aimed to examine nurses’ perception of the nurse-parent interaction at CHCs and assess barriers to and facilitators of interaction intended to promote healthy weight gain and prevent obesity. Specifically, we aimed to (i) examine how nurses determine or identify a child’s weight status (i.e. normal weight, under- or overweight, and obesity), (ii) determine who (nurse or parent) initiates discussion about a child’s overweight/obesity, (iii) examine whether a child’s overweight/obesity was too sensitive to discuss with the parents; (iv) investigate nurses’ views on parental responses to their child’s overweight/obesity; and (v) describe health promoting actions and prevention of childhood obesity at CHCs.
Discussion
The findings reported here represent CHC nurses’ view of their interactions with parents of preschool children with overweight or obesity. Interviews were held in widespread geographical areas of CHCs comprising a variety of Swedish demographic and socioeconomic characteristics. By default, CHCs in Sweden have a long tradition of growth monitoring and a very high uptake rate (i.e. > 99% of children visit the nurse’s office at least six times) [
9], which gives obesity prevention a key position at CHCs. Consequently, assessment of a child’s weight status was a central theme in the topic guide. Our results showed that all CHC nurses used the traditional weight-for-height chart, which plots two different growth curves. However, nurses did not always use the recommended BMI chart [
10,
11]. Those who used the BMI chart reported several benefits. Weight problems were easier to detect compared to height and weight charting, which concurs with the results of other studies [
26]. In addition, the BMI chart is easy to understand by parents of all educational backgrounds. Visualization of overweight or obesity with the BMI chart favors objective communication. Consistent with previous qualitative studies, nurses in our study were able to set aside their personal and subjective perceptions about a child’s weight status [
18]. Nurses applied a participatory approach, displaying children’s charts and informing parents about their child’s growth pattern. In a 2005 survey of CHC nurses (n = 270, response rate 80%) in our study region, only 14% reported using the BMI chart. Consequently, the county of Västra Götaland decided to recommend use of the BMI chart [
27]. However, the CHCs in this study did not seem to follow those recommendations fully, possibly due to a lack of quality assurance methods or a lack of computers or computer skills.
Health professionals (e.g. CHC nurses) are ideally placed to identify children at risk for obesity and to play an active role in obesity prevention [
28]. By plotting a child’s BMI at all health visits and using any change in BMI to identify excess weight gain, CHC nurses can activate obesity prevention strategies [
28,
29]. Despite strong recommendations by the American Academy of Pediatricians, the BMI chart remains underused [
26,
30].
Several studies also underline the importance of early obesity prevention [
2,
5,
6,
31,
32]. Whitaker et al. [
31] showed that children with obesity under the age of three years are at low risk of obesity in adulthood. Harrington et al. [
32] concluded that the critical period for preventing childhood obesity is during the first two years of life. In our study, nurses described their CHC standard procedures to administer a questionnaire regarding the child’s development, food and activity habits at 18 months and 2½ years of age as a valuable opportunity and a facilitator for confidential and structured dialogues with all parents of children under the age of three years. Thus, the risk that parents would feel offended or react negatively decreases since, at that age, the focus is not on the child’s BMI but on lifestyle habits and behaviors.
Another theme involved determining who initiated discussions about an issue regarding a child’s weight status. Nurses responded that they usually took the initiative, although some concerned parents also initiated the discussion. Because parents have a particular interest in their child’s growth, it is reasonable to expect that they would initiate a discussion if the child gains weight too rapidly. However, it may be unrealistic to assume that parents who lack an accurate perception of their child’s overweight or obesity could initiate a discussion. Several studies reported that parents of children with overweight or obesity underestimate their children’s weight status [
15,
16]. The Identification and Prevention of Dietary- and Lifestyle-Induced Health Effects in Children and Infants study (IDEFICS) investigated two to nine-year old children and their parents in eight European countries. Between 50% and 77% of parents of children with overweight (n = 1,968) perceived their children to be of normal weight and 70% of the parents of children with obesity (n = 1,072) perceived their children as only “slightly too overweight” [
16]. However, it is unknown whether these parents had received accurate information about their child’s weight status at a CHC or the school health service. Because CHC nurses in Sweden have access to the child’s growth charts, they can objectively judge the child’s weight status and communicate their findings to the parents, who lack access to the charts. Another advantage at the preschool age is that parents are always present when a nurse measures their child’s growth at CHC, which facilitates the communication of the findings, as compared to school aged children when parents are not present when measurements are made and need to receive notification by other means.
Several studies have observed that childhood obesity is a sensitive topic because healthcare professionals fear offending parents [
17,
18,
33]. Our study supports these findings. Nurses sometimes avoid the word obesity, using “overweight” to describe both overweight and obesity, possibly due to a desire to be empathetic. This approach may confuse the definition of overweight and obesity and make communication with parents less clear. Nurses also reported that they sometimes retreated because of parents’ reactions. Others emphasized that avoidance was never an option, even when parental responses were strained. They explained that they relied on ethical values and stressed children’s right to a healthy start in life. One nurse referred to the United Nations Convention on the Rights of the Child (UNCRC) which stipulates “the right of the child to the enjoyment of the highest attainable standard of health” (art. 24) [
34]. These values strengthened the nurses’ resolve to initiate a discussion with parents because they saw this as their mission.
Parental responses and nurses’ attitudes indicated that obesity prevention at CHC is both an organizational and an emotional issue. Our results discerned two subthemes of parental responses: (i) cooperative and help-seeking parents who easily benefited from CHC resources (i.e. positive responses) and (ii) parents who responded negatively, did not attend extracurricular health visits or went to another CHC. The lack of options for reaching these parents revealed an opportunity gap in supporting their children. Good health and equal care on equal terms for the entire population is expressed in Swedish law [
35]. Moreover, Sweden has ratified the UNCRC [
34]. Parental cooperation with lifestyle changes is fundamental to the success of obesity prevention [
29]. CHCs must reach out to parents who respond negatively when nurses inform them about their child’s obesity. According to Mikhailovich and Morison [
19], healthcare professionals should expect a wide range of parental responses and a critical period in communicating “difficult” news. Parents may fear that their child will be stigmatized. Therefore, healthcare providers need to create an environment of support and partnership [
19].
Some parents deliberately struggle to make their toddler overweight. Nurses explained that such parents believe that overweight represents health and successful parenting, in line with Baughcum et al. [
36]. In agreement with others [
16,
37], some nurses in this study also interpreted parents’ desire for a “chubby child” as an irrational concern that their child might become underweight.
CHC actions were integrated into the regional CHC program [
10]. The nurses aimed to give nutrition advice at all health visits and to follow the development of the child and the well-being of the family. Therefore, growth measurements are not only a technical procedure but also part of a holistic view of the child and family in the context of the family’s social circumstances. A recent study of CHCs in western Sweden reported that nurses expressed uncertainty about determining a child’s weight status compared to BMI and also about counseling parents when their child was overweight or obese [
38]. In yet another Swedish CHC study [
39], audiotapes of conversations with parents revealed infrequent attention to dietary and physical activity behaviors. The study ranked 23 topics of conversation according to the median proportion of total session time. In descending order, dietary habits ranked at number 4 (9.5%) and physical activity behaviors first at number 14 (3.5%).
The nurses followed basic CHC guidelines and referred children with obesity to a physician and frequently also to a dietitian [
10]. Parent groups at CHC were only held for parents of children younger than one year. When children began to eat the same food as the family, CHCs could no longer gather parents easily and inform them about healthy eating habits, often because parents had returned to work and had less time. Moreover, CHCs had difficulty implementing parent groups in areas with high immigration rates and low socioeconomic status because parents often did not attend the sessions. This was disclosed through the purposive sampling selection of a diverse geographical and demographic background. This is also a barrier because health-promoting activities must equally reach all types of families. In addition, the prevalence of obesity in Sweden is higher in areas with high immigration [
40]. In different areas of Stockholm, families with low purchasing power strongly correlate with obesity in four-year-old children born in 2006 [
41]. Wallby and Hjern [
42] showed that low income and foreign born mothers had lower rates of participation in parental groups at CHC in a Swedish county. In the Swedish IDEFICS health survey, families characterized by single parenthood, foreign background, and low education and income were underrepresented compared to the general population [
43]. Therefore, CHCs need to strengthen health promoting and prevention actions for young children to ensure that such families receive access that equals that of affluent families and cooperative parents.
In the theme of lifestyle patterns, our results showed that parents are influenced by the obesogenic environment, which corresponds to the WHO population strategy [
1] that seeks to shift the responsibility from the individual to societal stakeholders in tackling health risks. Even though the majority of parents try to do their best, they may need to be “super parents” to resist the influences of today’s obesogenic environment [
44,
45]. In the present study, several nurses observed that food marketing heavily influences parents’ choices of industrialized and convenience foods. This finding concurs with parental views about factors that influence eating behaviors in their two to eight-year old children, as expressed in focus group discussions held in IDEFICS [
46]. Our nurses observed that many parents underestimate children’s need for active play and allow too sedentary activities. For example, it was not unusual to see children sitting in a stroller when they were old enough to walk, which concurs with IDEFICS’ parental focus group discussions about children’s physical activity [
47], i.e. parents frequently mentioned that their children did not like to walk. However, it is important to recognize the multicomponent and complex web of causes of the obesity epidemic [
48]. There are several opportunities for obesity prevention, not only at the individual level but also at the national and community levels: for example, new and improved food labeling, reduced advertisements for unhealthy foods and beverages, increased access to green spaces and physical activity and social marketing on what and how much to eat and how to reverse the culture of long work days [
48,
49].
Strengths and limitations
A strength of this study is that 15 nurses from different geographical parts of Sweden, which comprise a variety of population demographic characteristics, gave their view of health promotion and obesity prevention interactions with parents. The majority also had long-standing experience as CHC nurses and can be considered experts in the field. Our nurses offered full and vivid descriptions of the predetermined themes. The professional background of the interviewer (SR), a pediatric nurse with practical experience of working with parents and children as well as professional concepts and practices, may have strengthened confidence during the interviews and contributed to the sharing of informants’ experiences. We assured rigorous analysis (Table
2) by preparing and organizing the content analysis process, following a structure that progressed from meaning unit to code, subtheme and theme. The extended and supportive findings of others increased the strength of our directed and deductive approach [
21,
22]. Conformability was ensured because the authors agreed with the findings and brought their unique perspectives and experience to the study. The research group critically discussed all categorizations into subthemes and themes.
To some extent, the limitations of this study are shared by other qualitative studies as part of methodological constraints. For example, those who decided to participate were presumably motivated to give their full view of the subject of interest, while those with a contrary view were not heard. Furthermore, because parents did not participate in the study, their voices were unheard. Consequently, parents could not dispute or agree with statements about the parents. Consequently, the parental views reported in this study are told through the eyes and perspective of the nurses. However, we still believe that it is possible to transfer their perspectives to similar settings and conditions.
