Unpacking the Public Health Triad of Social Inequality in Health, Health Literacy, and Quality of Life-A Scoping Review of Research Characteristics.

Social inequalities in health, health literacy, and quality of life serve as distinct public health indicators, but it remains unclear how and to what extent they are applied and combined in the literature. Thus, the characteristics of the research have yet to be established, and we aim to identify and describe the characteristics of research that intersects social inequality in health, health literacy, and quality of life. We conducted a scoping review with systematic searches in ten databases. Studies applying any design in any population were eligible if social inequality in health, health literacy, and quality of life were combined. Citations were independently screened using Covidence. The search yielded 4111 citations, with 73 eligible reports. The reviewed research was mostly quantitative and aimed at patient populations in a community setting, with a scarcity of reports specifically defining and assessing social inequality in health, health literacy, and quality of life, and with only 2/73 citations providing a definition for all three. The published research combining social inequality in health, health literacy, and quality of life is heterogeneous regarding research designs, populations, contexts, and geography, where social inequality appears as a contextualizing variable.

Stories of paediatric palliative care: a qualitative study exploring health care professionals' understanding of the concept.

BACKGROUND: By sharing patient stories, health care professionals (HCPs) may communicate their attitudes, values and beliefs about caring and treatment. Previous qualitative research has shown that HCPs usually associate paediatric palliative care (PPC) with death or dying and that they find the concept challenging to understand and difficult to implement. Attending to HCPs' stories may provide a richer account of their understanding of PPC. Thus, the aim of this study was to explore PPC stories narrated by HCPs to gain increased insight into their understanding of what PPC entails. METHODS: This qualitative study collected data from four focus group interviews with 21 HCPs from different units in two Norwegian hospitals. Stories told by the HCPs to illustrate their comprehension of PPC were analysed following thematic analysis procedures. RESULTS: Four themes were identified illustrating what PPC meant to the participants: creating spaces for normality, providing tailored support for the family, careful preparations for saying goodbye and experiencing dilemmas and distress. The stories centred on family care, particularly relating to dramatic or affective situations when the death of a child was imminent. CONCLUSION: The stories reflect how the HCPs view PPC as a specific field of health care that requires particular professional sensitivity, including good communication, collaboration and planning. Thus, the HCPs in this study demonstrated knowledge about the core qualities needed to succeed in PPC. However, similar to previous research, the stories illustrate that how HCPs speak about PPC is strongly associated with end-of-life care, and by that the HCPs do not capture the breadth of the PPC concept. The findings highlight the importance of increasing knowledge about the meaning and content of PPC among HCPs in order to maintain quality of life for all children with life-limiting or life-threatening conditions throughout their illness trajectory.

Making room for life and death at the same time - a qualitative study of health and social care professionals' understanding and use of the concept of paediatric palliative care.

BACKGROUND: The concept of pediatric palliative care (PPC) is applied differently within the healthcare system and among healthcare professionals (HCPs). To our knowledge, no studies have investigated how multidisciplinary HCPs understand the concept of PPC and the aim of this study was to explore the concept of PPC from the view of HCP in a paediatric setting. METHODS: We employed an explorative and descriptive design and conducted four focus groups with a total of 21 HCPs working in hospitals with children in palliative care. The data were analysed using qualitative content analysis. RESULTS: The data analysis of the concept of pediatric palliative care resulted in two themes. The first theme "A frightening concept that evokes negative emotions," contains categories to explore the meaning, named "An unfamiliar and not meaningful concept, "A concept still associated with death and dying" and "Healthcare professionals' responsibility for introducing and using the concept and, to obtain a common meaning." The second theme was named "A broad and complementary concept," containing the categories "Total care for the child and the family," "Making room for life and death at the same time" and "The meaning of alleviation and palliative care." CONCLUSIONS: The included HCPs reflected differently around PPC but most of them highlighted quality of life, total care for the child and the child's family and interdisciplinary collaboration as core elements. Attention to and knowledge among HCPs might change the perception about PPC from a frightening concept to one that is accepted by all parties, implemented in practice and used as intended. However, our study reveals that there is still some work to do before PPC is understood and accepted by all those involved.

Infant colic, young children's temperament and sleep in a population based longitudinal cohort study.

BACKGROUND: Colic and sleep problems are common among infants, constitute challenges and distress for parents, and are often reasons for seeking help from health professionals. The literature debates whether infant colic and sleep problems are linked together or not. Further, limited evidence exists on how colic impacts on child temperament and sleep during early childhood. Thus, the purpose of this study was to increase our knowledge of the characteristics of infants with a history of colic compared to infants without, and to study how infant colic is associated with the development of child temperament and sleep over time. METHODS: The study is based on The Norwegian Mother, Father and Child Cohort Study (MoBa), a population-based cohort study conducted by the Norwegian Institute of Public Health. This sample contains 88,186 mothers and children. Data was retrieved from questionnaires distributed to mothers at recruitment (in pregnancy) and when the child was 6 months, 18 months, 3 years, and 5 years. Data was analysed using linear mixed models and GLM models for repeated measures. RESULTS: At 6 months, infants with reported colic are described as fussier, present more sleeping problems, are breastfed less, and the families visit the child health centre more often when compared to the non-colic group. Mothers of children with reported colic perceive their children's temperament significantly more challenging from the age of 6 months to 5 years. Further, children with reported colic were more likely to sleep less than recommended (22%) and to have more frequent night awakenings (14%) than usual for their age (6 months to 5 years). CONCLUSION: Infant colic often occurs together with other signs of regulatory problems which may amplify the load on the parents. Moderate differences in temperament and sleep-problems across time, between those with colic and those without, indicate that the diagnosis of colic is moderately associated with later behavioural difficulties. However, it is demanding for the parents, and important to be aware of and act upon symptoms of colic in the child health centres to reduce the parents' load and prevent adverse long-term outcomes.

Factors associated with maternal overall quality of life six months postpartum: a cross sectional study from The Norwegian Mother, Father and Child Cohort Study.

BACKGROUND: Having good Quality of Life (QoL) is essential, particularly for women after childbirth. However, little is known about the factors associated with maternal QoL after giving birth. We aimed to investigate the relationship between characteristics of the mother (socio-demographic variables), selected symptoms (depression and joy/anger), health perception (perception of birth) and possible characteristics of the environment (infant temperament, colic, sleep, parental relationship), with mothers' overall quality of life when the child is 6 months of age. METHODS: This study is based on the Norwegian Mother, Father and Child Cohort Study (MoBa), conducted at the Norwegian Institute of Public Health from June 1999 to December 2008, which included a total of 86,724 children. Maternal QoL was assessed by the Satisfaction With Life Scale. Joy and anger were measured using the Differential Emotional Scale, mothers' mental health was assessed using the Edinburgh Postnatal Depression Scale and satisfaction with relationship was measured using the Relationship Satisfaction Scale. Child temperament was measured using the Infant Characteristics Questionnaire and colic, sleep duration and feelings related to childbirth were assessed by mothers' reports. The associations between life satisfaction and selected variables were analysed using stepwise multiple linear regression models, and the results are presented as effect sizes (ES). RESULTS: Maternal feelings of joy of having a baby (ES = 0.35), high relationship satisfaction (ES = 0.32), as well as having a baby with normal sleep (ES = 0.31), are factors associated with higher maternal overall QoL. Postnatal depression was negatively associated with mothers' QoL, and infant colic or child's temperament (fussiness) showed no such association with mothers' QoL. CONCLUSIONS: Health professionals and clinicians should focus on infants sleep but also on supporting joy of motherhood and strengthening relationships of the new parents when they develop health interventions or provide counselling to new mothers and their families.

Students' top 10 priorities of research uncertainties on students' sleep: a pragmatic James Lind Alliance approach.

OBJECTIVES: Inspired by the James Lind Alliance (JLA) user involvement approach, the aim of the present study was to identify the top 10 uncertainties for sleep research raised by students in higher education, and to discuss our experiences with adapting the JLA method to a student population. DESIGN: The study design is a pragmatic JLA approach, including a priority setting partnership within the field of sleep, collection of sleep-related research uncertainties as reported by students in higher education, sorting of the uncertainties and a final identification of the top 10 uncertainties through collaborative work between researchers, students, stakeholders and experts in the field. Uncertainties were collected using a one-question online survey: 'as a student, which question(s) do you consider to be important with regards to sleep?'. A variety of approaches were applied to promote the survey to the students, including social media, radio, the university website, stands in university cafeterias and a sleep stunt. NVivo V.12 was used to code and sort the questions. SETTING: A higher education institution in Norway. PARTICIPANTS: 555 students. RESULTS: The data collection provided 608 uncertainties, and the following prioritised top 10: (1) screen time, (2) stress, (3) educational achievements, (4) social relations, (5) mental health, (6) physical activity, (7) indoor environment, (8) substance abuse, (9) shift work and (10) sleep quality. Despite successful data collection, we found sleep to be a broad topic, and defining specific questions throughout the sorting and verification process proved difficult. CONCLUSIONS: We identified the prioritised top 10 research uncertainties as reported by students in higher education, ranking screen time first. However, the process was time and resource consuming. The research uncertainties addressed by the students showed great diversity, characterised by heterogeneity and a lack of specificity, making verification of the uncertainties challenging.

Association between colic and sleep problems in infancy and subsequent development, emotional and behavioral problems: a longitudinal study.

BACKGROUND: Sleep and colic problems in infancy have been linked to adverse health outcome, but there is limited knowledge of the association between sleep and colic problems in infancy and subsequent development, emotional and behavior problems in young children. The aim of the present study was to examine whether there is an associations between infants' crying and sleep problems at 6 months and behavioral and development problems at 18 months, 3 and 5 years. METHODS: This study is based on the Norwegian Mother, Father and Child Cohort Study (MoBa), conducted at the Norwegian Institute of Public Health from June 1999 to December 2008. A total of 86,724 children were included. Colic and sleep (sleep duration, nocturnal awakenings and easy to put to bed) was assessed by mother-reports. Z-scores were used to assess differences between groups of children (e.g. having colic or not, having a sleep problem or not). Emotional and behavioral problems were measured with items from the Child Behavior Checklist. Development problems were measured with items from The Ages and Stages Questionnaire. RESULTS: Infants with colic scored significantly lower on development at 5 years (B=-0.10, CI [- 0.14 to - 0.06]) and higher on internalizing problems both at 3 years (B=0.15. CI [0.11 to 0.18]) and 5 years (B=0.17. CI [0.12 to 0.21]) than the reference population. Children who awoke frequently and were more difficult to put to bed at 6 months scored significantly lower on development at 18 months and 3 and 5 years, and higher on internalizing behavior problems at 3 and 5 years (B=0.18 and B=0.16). Children with shorter sleep duration at 6 months had more internalizing behavior problems at 3 years (B=0.14. CI [0.07 to 0.21]) and 5 years (B=0.15. CI [0.05 to 0.25]) than the reference population. CONCLUSIONS: Colic and sleep problems early in life should be taken into account as risk factors for development and behavioral problems within the first 5 years of a child's life.

Evaluating a Web-Based Health-Promoting Dialogue Tool in School Health Services: Feasibility and User Experiences.

Adolescence is a sensitive period in life and a time to redefine and learn new skills. In Norway, school health services provide individual health-promoting consultations with all eighth-grade students. As an aid to support these consultations, a dialogue tool called SchoolHealth was developed using a co-creation approach. SchoolHealth consists of a web-based health information form designed to be completed by the students and generates individual feedback reports to help the school nurses to prepare for the consultation and tailor it to the individual student's need. Our aims were to evaluate the feasibility and user experiences of SchoolHealth among students and school nurses using a mixed methods approach. A total of 79 eighth-grade students (69% of those invited) and four school nurses from three schools participated. Analyses indicated that SchoolHealth was feasible, promoted reflection among students, and helped prepare students and school nurses for the consultation.

Associations between menopausal hormone therapy and sleep disturbance in women during the menopausal transition and post-menopause: data from the Norwegian prescription database and the HUNT study.

BACKGROUND: Impaired sleep is common in menopausal women. The aim was to examine associations between uses of systemic menopausal hormone therapy (MHT) and sleep disturbance in a large population sample. METHODS: Female participants aged 45 to 75 years were selected from the Norwegian Health Study in Nord-Trøndelag (HUNT3, 2006-2008) (N = 13,060). Data were linked to the Norwegian Prescription Database, identifying use of prescribed MHT and use of sleep medication. Data were analyzed using multiple linear regression. RESULTS: In total, 996 women used systemic MHT (7.6%), with the highest prevalence of 10.3% among women 55 to 64 years of age. Despite high reports of frequent nocturnal awakening (24.7%) and high reports of hot flashes, use of MHT was low in this large population based survey. Although MHT use was associated with more sleep disturbance in unadjusted analyses, the association was not significant after adjusting for relevant covariates. Using sleep medication, reporting poor health, tobacco and alcohol use, doing daily exercise, having higher levels of anxiety, and being less satisfied with life were factors showing the strongest associations with sleep disturbance. CONCLUSION: The lack of association between MHT and sleep disturbance suggests that other factors, such as self-perceived good health, a healthy lifestyle and anxiety/depression, are more relevant to sleep than MHT.

Bullying in School: Importance of and Challenges Involved in Talking to the School Nurse.

Bullying has negative consequences for health and quality of life of students. This study is part of a pilot project, "School Health," which included a web-based questionnaire completed by students before a consultation with the school nurse. The aim of this study was to explore how students experience answering questions about bullying before an individual consultation and how they talk about bullying with the school nurse. This study had qualitative design with individual and focus group interviews and involved 38 students aged 13-14 years, both boys and girls, from three schools. Data were analyzed according to Kvale's three levels of interpretation within a phenomenological and hermeneutic perspective. The students found it difficult to report being bullied. They expressed confidence in the school nurse and liked talking with her. Some complained about the school environment and reported that having a friend was important.

Implementing guidelines for preventing, identifying and treating adolescent overweight and obesity-School nurses' perceptions of the challenges involved.

AIMS AND OBJECTIVES: To gain a better understanding of school nurses' perceptions of the challenges involved in implementing national guidelines on managing overweight and obesity in adolescents. BACKGROUND: National guidelines for the management of childhood overweight and obesity are developed in many countries to translate scientific knowledge into practice. However, several challenges are involved in their implementation. DESIGN AND METHODS: A qualitative design with focus group interviews was chosen for data collection. Six focus group interviews with 21 school nurses were conducted. Data were analysed by qualitative content analyses. RESULTS: National guidelines provided new directions for managing overweight and obesity in school health services. School nurses were assigned new tasks and responsibilities, which they felt they were not sufficiently prepared for, nor were they supported by extra resources. Challenges in implementation of the guidelines were identified at various levels: system level (implementation strategy, available resources, training and support, professional collaboration, referral options); individual school nurse level (perceived competence, burden of responsibility, attitudes and emotions); subject level (sensitivity of weight-related issues); and professional level (scepticism to a body mass index cut-off of 25 kg/m2 as the starting point for intervention). CONCLUSIONS: School nurses felt overwhelmed in terms of implementing the guidelines. This indicates barriers not being sufficiently identified or acted upon during implementation. Further, the nurses' scepticism about the body mass index cut-off for intervention, and their experience that measuring and follow-up of adolescents' weight development was their responsibility alone, indicates that important discussions are needed on this as an adequate measure as well as on the professional division of responsibilities. RELEVANCE TO CLINICAL PRACTICE: Having a proper strategy for implementation, and ensuring that necessary clinical structures and resources are available, is crucial. Including school nurses in developing and implementing such strategies is vital for success in implementing national guidelines.

Psychosocial factors are strongly associated with insomnia in users and nonusers of prescribed sleep medication: evidence from the HUNT3 study.

OBJECTIVE: The aim of this study was to examine how neuroticism, stressful life events, self-rated health, life satisfaction, and selected lifestyle factors were related to insomnia both by sex and among users and nonusers of prescribed sleep medication (PSM). DESIGN: Cross-sectional data from the Norwegian Nord-Trøndelag Health Study (HUNT3, 2006-2008), a population-based health survey, were linked to individual data from the Norwegian Prescription Database. METHODS: Logistic regression analyses were used to investigate the associations between the selected variables and insomnia in both males and females and among subjects using and not using PSM. Individuals were considered to have a presumptive diagnosis of insomnia disorder if they reported difficulty with sleep initiation, sleep maintenance, or early morning awakening several days per week for the last 3 months. PSMs were categorized as anxiolytics or hypnotics; the dose was estimated according to defined daily dose (DDD). RESULTS: Of the total 50,805 participants, 6,701 (13.2%) used PSM. The proportions of PSM users were larger among elderly participants. Increased risk of insomnia was strongly associated with poor self-rated health and higher level of neuroticism. These associations were evident for both sexes and were similar among both users and nonusers of PSM. Low satisfaction with life was strongly related to insomnia, but only among nonusers of PSM. Increased doses of PSM were not associated with reduced likelihood of insomnia. CONCLUSION: Insomnia is a problem among both users and nonusers of PSM and is associated with psychosocial factors. Our findings suggest that successful treatment for sleep problems should take individual variation into account, such as age, sex, personality traits, satisfaction with life, and health perception.

Targeting and tailoring an intervention for adolescents who are overweight: some ethical concerns.

There are important ethical issues to be examined before launching any public health intervention, particularly when targeting vulnerable groups. The aim of this article is to identify and discuss ethical concerns that may arise when intervening for health behavior change among adolescents identified as overweight. These concerns originate from an intervention designed to capacitate adolescents to increase self-determined physical activity. Utilizing an ethical framework for prevention of overweight and obesity, we identified three ethical aspects as particularly significant: the attribution of responsibility for health behavior, liberty to choose, and the effect on the participants' psychosocial well-being. It is discussed whether and how measures can be taken to deal with these aspects. It seems evident that the ethical aspects are mainly concerned with the vulnerability of adolescents identified as overweight. However, we claim that when individual feedback and counseling is provided, tailored interventions have a unique potential to empower adolescents to make ethically anchored decisions about their own health behavior.

The outcomes of a 12-week Internet intervention aimed at improving fitness and health-related quality of life in overweight adolescents: the Young & Active controlled trial.

BACKGROUND: Overweight and obesity among adolescents may have consequences, with potentially lasting effects on health and health-related quality of life (HRQoL). Excess weight is also associated with decreases in physical activity and cardiorespiratory fitness. The aim of the current study was to investigate the short-term effects of a 12-week Internet intervention in a primary care setting intended to increase cardiorespiratory fitness and HRQoL among overweight and obese adolescents. METHODS: In this controlled trial, participants (13-15 years) were non-randomly allocated to an intervention- or a control group. The intervention group received 12-weeks access to an online program providing tailored physical activity counseling based on principles from Self-determination Theory and Motivational Interviewing. The control group received standard follow-up by the school nurses. The primary outcome measure of cardiorespiratory fitness was determined using a shuttle run test. The secondary outcomes: HRQoL, leisure time exercise, body image and self-determined motivation for physical activity and exercise, were assessed by self-report measures. Age- and gender-adjusted body mass index (BMI) was calculated based on measurements of height and weight. To compare pre-to post intervention differences within groups, a paired samples t-test was used while crude differences between groups were analyzed with an independent samples t-test. RESULTS: Of the 120 participants, 108 completed the study, 75 in the intervention group and 33 in the control group. Exposure to the intervention had a small effect on cardiorespiratory fitness (0.14; 95% CI [0.01;0.28]; P = 0.04), and a moderate effect on HRQoL (5.22; 95% CI [0.90; 9.53]; P = 0.02). Moreover, the control group increased significantly in BMI, yielding a moderate preventive effect on BMI (-0.39; 95% CI [-0.74;-0.03]; P = 0.03) for the intervention group. CONCLUSION: The results suggest that the Internet intervention with tailored physical activity counseling can have beneficial short-term effect on cardiorespiratory fitness, HRQoL and BMI among adolescents with overweight and obesity. TRIAL REGISTRATION: ClinicalTrials.gov NCT01700309.

The relationship between fitness and health-related quality of life and the mediating role of self-determined motivation in overweight adolescents.

AIM: To examine the relationship between cardiorespiratory fitness (CRF) and health-related quality of life (HRQoL) among overweight adolescents and to test whether this relationship is mediated by body image (BI) and self-determined motivation for physical activity (PA) and exercise. METHODS: One hundred and twenty adolescents identified as overweight or obese were recruited through the school health service. The participants completed self-report instruments measuring HRQoL, BI and self-determined motivation for physical activity and exercise in addition to a 20 m shuttle-run test, and body mass index was calculated. Confirmatory factor analysis was conducted to evaluate the hypothesised five-dimensional structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) used to measure self-determined motivation. Associations between the study variables were explored using univariate linear regression. Mediation was tested by a multistage regression approach. RESULTS: The five-dimensional model of BREQ-2 showed acceptable fit for the data. We revealed a statistically significant association between cardiorespiratory fitness and HRQoL (4.16 [0.3-8.02]; p < .05). CRF failed to affect BI in the first mediation equation. Hence, body image was excluded from further analyses. However, self-determined motivation proved to mediate the relationship between CRF and HRQoL. CONCLUSIONS: The results of this study suggest that the motivational mechanisms related to fitness can contribute to explain the association between CRF and HRQoL in overweight adolescents. The findings are important from a public health point of view and should be taken into account in the development of PA interventions for overweight and obese adolescents for the potential enhancement of their physical and psychosocial well-being.

Do public health nurses in Norway promote information on oral health?

BACKGROUND: (i) to describe oral health counselling in Norway to parents with infants and toddlers, ii) to assess existing collaboration and routines in oral health matters between nurses and personnel in the PDS, iii) to evaluate to what extent oral health was integrated in the basic educational curriculum of public health nurses. METHODS: This study was based on two separate surveys: the sample of Study I was 98 randomly selected child health clinics. A questionnaire covering oral health promotion counselling of parents with young children was returned by 259 nurses. Study II was a telephone survey addressing teachers of public health nurses at the eight educational institutions in Norway. RESULTS: The response rate in Study I was 45%. Nutrition (breast feeding, diet) was the health subject most often prioritized in the counselling targeting parents of young children (by 60% of the nurses). Oral health was not among the first priority counselling subjects. The subject was seldom spontaneously mentioned by parents. Seventy percent of respondents reported (agreed or totally agreed) that they managed to provide information parents needed and 72% believed that the information they gave influenced parents' health behaviours. Seven nurses (5.2%) responded that they agreed with the statement that the information they gave only slightly influenced parents' health behaviour. Lack of time was mentioned as being a problem. Approximately half of the nurses (48%) had regular contact with the PDS for the 0-3 year-old children, but only a quarter of the nurses claimed that children's teeth were routinely examined at the child clinics. Some forms of previously established contact with the PDS enhanced the likelihood of nurses' referrals. Oral health was a minor part of the educational curriculum for public health nurses; at three institutions, the subject was totally absent. CONCLUSION: Collaboration between nurses and the PDS in Norway could be improved. Oral health should have a bigger place in the basic educational curriculum.

Adolescents' perceptions of quality of life: what it is and what matters.

AIM: The aim of this study is to explore and describe adolescents' own perceptions of quality of life; what it is and what matters. BACKGROUND: Quality of life has become an important concept in evaluating health care, in both child and adult populations. As nurses concerned with quality of life and well-being, it is important for us to identify the main factors that contribute to the promotion and sustenance of young people's well-being. DESIGN: A qualitative hermeneutic design was chosen. METHOD: The method was in-depth interviews with 31 healthy adolescents (14-15 years) in the school health service. The interviews were taped, transcribed and analysed as text according to Kvale's three contexts of interpretation: self-understanding, critical common sense and theory. RESULTS: According to the adolescents, quality of life is about the positive cycles of life. Feeling good, being satisfied with oneself and having an overall positive attitude are in most cases described as the starting points of a positive cycle. To get into and stay in the positive cycle, a positive self-image, good friends and good family relations are important. Consequently, adolescents' quality of life is threatened when these factors are negative. Friends seem to be the most significant factor. It is extremely difficult to be without friends and none of the adolescents would admit that they were, not even to themselves, although it was rather obvious in some cases. Self-image and popularity are factors associated with the ability to get friends. CONCLUSIONS: Understanding the adolescents' view of quality of life emphasises the importance of focusing on their psychosocial health and in particular their peer relations, to promote and sustain their quality of life. RELEVANCE TO CLINICAL PRACTICE: Knowledge about the factors most significant to adolescents' quality of life is applicable to all clinical settings where nurses meet adolescents; i.e., hospitals, outpatient clinics and school health services.

Perception of marital quality by parents with small children: a follow-up study when the firstborn is 4 years old.

Swedish couples' perceptions of their marital quality when their firstborn was 6 months old and then 4 years later were studied in 2002 and 2006, respectively. The results show that almost half of the 368 responding parents were satisfied with their marital relationship both in 2002 and 2006 as assessed by a modified Dyadic Adjustment Scale. However, a study of the various dimensions showed a significant decrease in marital quality. Housework and child care were perceived as having a greater strain on the relationship between couples who had had additional children during this period. Dyadic Sexuality and Dyadic Cohesion were the most significant predictors of marital quality. Covariates of marital quality in the group with additional children were "partner relation and parenthood perceived as a strain" and "perceived social support." The results emphasize the need for supportive interventions for parents with children aged 0 to 4 years.
