Childhood obesity is a global public health threat correlated with several comorbidities and increased mortality in adult life. Heredity and physical development concomitant with environment culture and lifestyle habits are contributing key factors for the onset of overweight. Non-genetic components related to unhealthy dietary and activity patterns shared in families, are environmental factors that are possible to prevent before habits are set. Research indicates that there are several barriers against the proper management of this often long-term condition, where preschool children are an understudied group. This thesis aims to investigate how the Child Health Care (CHC) nurses pursue the preventive work on childhood overweight and obesity in CHC and further, to explore parental risk factors in relation to overweight and obesity in children.
In the first study (Paper I), 18 nurses at 17 CHC centers in the southern part of Sweden were interviewed using semi-structured interviews with a phenomenographic approach. This study aimed to elucidate the conceptions of childhood overweight, including obesity, among nurses working in CHC. The analysis yielded 11 different conceptions from which emerged four categories of description; “Perception of childhood overweight changes”, “Overweight in younger children, a neglected concern”, “Overweight, a delicate issue” and “The importance of family lifestyle”. The results show that CHC nurses conceived overweight and primarily obesity in children to be an extensive and serious health problem, mainly due to parent’s lifestyle. Childhood overweight during infancy and their preschool years was conceived as a minor concern and further nurses perceived it as a provoking and sensitive issue that was difficult to define. Despite there being an adaption towards the acceptance of larger children, childhood overweight and obesity were considered to be undesirable by both the CHC and the Swedish society in general. Both nurses and parents were more concerned about the children’s appearance and the risk of their being bullied than about the children’s health. Nurses conceived that it was important to protect the parent-nurse relationship. Therefore in order not to jeopardize this relationship; the subject of childhood obesity was avoided.
The second study (Paper II) aimed to elucidate the CHC nurses conceptions of their preventive work with childhood overweight and obesity in CHC. Study II was conducted at 17 CHC units using semi-structured interviews with 18 CHC nurses in the southern part of Sweden. The interviews had a phenomenographic approach which elucidated seven conceptions, from which emerged two categories of description; “internal obstacles to nurses’ work with overweight in children” and “external obstacles to the management of overweight in children”. The results show that the CHC nurses work was conceived to be complicated and constrained by several obstacles. Nurses’ preventive work was affected by factors linked to personal traits, lack of sufficient knowledge and lack of several resources affecting their ability to conduct preventive work.
The third and the fourth study (Paper III and IV), were based on a crosssectional survey with a questionnaire administered to a stratified and randomized selection of parents to preschool children registered at CHCs in the southern part of Sweden. In total, 598 parents participated in the study, divided into 255 fathers and 343mothers to 372 children, i.e. 372 families.
The third study (Paper III), examined socio- and demographic parental risk factors for overweight and obesity in children and the frequency of overweight and obesity in the context of child health care.
Descriptive analyses were used to present the frequency of parental and childhood overweight and obesity, and logistic regression was used to estimate the relation between parental socio- and biodemographic factors and children’s risk for overweight or obesity. Our results show that the frequency of overweight and obesity was 14.5 % in children, 56.0 % in fathers and 36.5 % in mothers. A distressed financial situation in fathers (OR 2.85, CI 1.06-7.69) was associated with increased risk for overweight and obesity in children. After adjusting for potential confounders in mutually adjusted models, the aggregated results for both parents showed that mothers and fathers born outside of Sweden (OR 4.50, CI 1.55-13.12 and OR 4.94, CI 1.72-14.20) was the strongest risk factor for overweight and obesity in children.
The fourth and final study (Paper IV) aimed to investigate parental lifestyle habits as risk factors for overweight and obesity in children. The relation between parental lifestyle habits and children’s risk for overweight and obesity was analyzed using logistic regression. Our results show that there might be a trend indicating an increased risk for children to develop overweight and obesity if the father is a daily smoker (OR 4.11, CI 1.45-11.68) and the mother is physically inactive (OR 2.33, CI 1.11-4.90).
This thesis comprises four studies of both qualitative and quantitative character, with focus on nurses’ preventive work with childhood overweight and obesity in CHC and parental risk factors. Our findings identify multiple levels of barriers to the prevention work on childhood overweight. Nurses’ lack of sufficient knowledge, nurses’ negative conceptions of families with overweight problems, parents’ lack of awareness and the sensitive nature of the issue are circumstances that complicate nurses’ work. Additionally, society’s adaption to the increased proportion of children with overweight has led to an acceptance of excess weight in children. Further, parental risk factors were also identified. Parents being born outside Sweden was associated with increased risk of childhood overweight and obesity, as well as financial distress within the family. Further, the findings show a trend that indicates that paternal smoking and maternal physical inactivity might be factors associated with enhanced risk of overweight and obesity in younger children.
We conclude that there exists a need to supplement the existing nurse education in child health care by putting the accent on intensifying education related to childhood overweight and weight assessment, with emphasis on the younger child. Further, this thesis implies that there is a need to better prepare specialist nurse student’s clinical skills related to their encounters with families and children at risk for overweight and obesity, through raising their awareness of their own perceptions of overweight in young children. Childhood overweight should be recognized and prioritized in CHC, further, the implementation of research results needs to be prioritized in the clinical work. The identification of risk factors may help health care personnel to identify and target children in risky family environments.
