A Cross Sectional Comparison of Predisposing, Reinforcing and Enabling Factors for Lifestyle Health Behaviours and Weight Gain in Healthy and Overweight Pregnant Women

Healthful Eating Behaviors among Couples Contribute to Lower Gestational Weight Gain

Through longitudinal analysis from the GLOWING cohort study, we examined the independent and joint relationships between couples' eating behaviors and gestational weight gain (GWG). Pregnant persons (n = 218) and their non-pregnant partners (n = 157) completed an Eating Inventory. GWG was calculated as gestation weight at 36 weeks minus that at 10 weeks. General linear models were used to examine the relationships between GWG and the pregnant persons, non-pregnant partners, and couples (n = 137; mean of pregnant persons and non-pregnant partners) cognitive restraint (range 0-21), dietary disinhibition (range 0-18), and perceived hunger (range 0-14), with higher scores reflecting poorer eating behaviors. The adjusted models included race/ethnicity, education, income, marital status, and age. The pregnant persons and their non-pregnant partners' cognitive restraint, dietary disinhibition, and perceived hunger scores were 9.8 ± 4.7, 4.8 ± 3.2, and 4.4 ± 2.5 and 6.6 ± 4.6, 5.4 ± 3.4, and 4.7 ± 3.2, respectively. Higher cognitive restraint scores among the pregnant persons and couples were positively associated with GWG (p ≤ 0.04 for both). Stratified analyses revealed this was significant for the pregnant persons with overweight (p ≤ 0.04). The non-pregnant partners' eating behaviors alone were not significantly associated with GWG (p ≥ 0.31 for all). The other explored relationships between GWG and the couples' eating behaviors were insignificant (p ≥ 0.12 for all). Among the pregnant persons and couples, reduced GWG may be achieved with higher levels of restrained eating. Involving non-pregnant partners in programs to optimize GWG may be beneficial.

A cost-effectiveness evaluation of a dietitian-delivered telephone coaching program during pregnancy for preventing gestational diabetes mellitus

BACKGROUND

This study aimed to evaluate the cost-effectiveness of a telehealth coaching intervention to prevent gestational diabetes mellitus (GDM) and to calculate the breakeven point of preventing GDM.

METHODS

Data to inform the economic evaluation model was sourced directly from the large quaternary hospital in Brisbane, where the Living Well during Pregnancy (LWdP) program was implemented, and further supplemented with literature-based estimates where data had not been directly collected in the trial. A cost-effectiveness model was developed using a decision tree framework to estimate the potential for cost savings and quality of life improvement. A total of 1,315 pregnant women (49% with a BMI 25-29.9, and 51% with a BMI ≥ 30) were included in the analyses.

RESULTS

The costs of providing routine care and routine care plus LWdP coaching intervention to pregnant women were calculated to be AUD 20,933 and AUD 20,828, respectively. The effectiveness of the LWdP coaching program (0.894 utility) was slightly higher compared to routine care (0.893). Therefore, the value of the incremental cost-effectiveness ratio (ICER) was negative, and it indicates that the LWdP coaching program is a dominant strategy to prevent GDM in pregnant women. We also performed a probabilistic sensitivity analysis using Monte Carlo simulation through 1,000 simulations. The ICE scatter plot showed that the LWdP coaching intervention was dominant over routine care in 93.60% of the trials using a willingness to pay threshold of AUD 50,000.

CONCLUSION

Findings support consideration by healthcare policy and decision makers of telehealth and broad-reach delivery of structured lifestyle interventions during pregnancy to lower short-term costs associated with GDM to the health system.

Dietitian-led cluster randomised controlled trial on the effectiveness of mHealth education on health outcomes among pregnant women: a protocol paper

INTRODUCTION

Nutrition education is the cornerstone to maintain optimal pregnancy outcomes including gestational weight gain (GWG). Nevertheless, default for appointments is common and often lead to suboptimal achievement of GWG, accompanied with unfavourable maternal and child health outcomes. While mobile health (mHealth) usage is increasing and helps minimising barriers to clinic appointments among pregnant mothers, its effectiveness on health outcomes has been inconclusive. Therefore, this study aimed to address the gap between current knowledge and clinical care, by exploring the effectiveness of mHealth on GWG as the primary outcome, hoping to serve as a fundamental work to achieve optimal health outcomes with the improvement of secondary outcomes such as physical activity, psychosocial well-being, dietary intake, quality of life and sleep quality among pregnant mothers.

METHODS AND ANALYSIS

A total of 294 eligible participants will be recruited and allocated into 3 groups comprising of mHealth intervention alone, mHealth intervention integrated with personal medical nutrition therapy and a control group. Pretested structured questionnaires are used to obtain the respondents' personal information, anthropometry data, prenatal knowledge, physical activity, psychosocial well-being, dietary intake, quality of life, sleep quality and GWG. There will be at least three time points of data collection, with all participants recruited during their first or second trimester will be followed up prospectively (after 3 months or/and after 6 months) until delivery. Generalised linear mixed models will be used to compare the mean changes of outcome measures over the entire study period between the three groups.

ETHICS AND DISSEMINATION

Ethical approvals were obtained from the ethics committee of human subjects research of Universiti Putra Malaysia (JKEUPM-2022-072) and medical research & ethics committee, Ministry of Health Malaysia: NMRR ID-22-00622-EPU(IIR). The results will be disseminated through journals and conferences targeting stakeholders involved in nutrition research.

A review of the behaviour change techniques used in physical activity promotion or maintenance interventions in pregnant women

BACKGROUND

The proportion of women meeting the recommended physical activity requirement is low. Evidence suggests behaviour change techniques (BCTs) can be effective in initiating and maintaining behaviour change and improving physical activity.

PURPOSE

To synthesise the evidence related to the attributes of BCT-based physical activity interventions targeted at pregnant women.

METHODS

A systematic search of studies was made. Randomised controlled trials aiming to improve or maintain physical activity in pregnant women were included. Trials were categorised into 'very promising', 'quite promising', or 'non-promising' according to the intervention effectiveness. One-way analysis of variance was used to determine the difference in mean BCTs implemented in promising/ non-promising studies.

FINDINGS

A total of 18,966 studies were identified and 10 studies were included. 'Problem solving', 'social support (unspecified)', 'graded tasks', 'goal setting (behaviour)', 'instruction on how to perform a behaviour', 'self-monitoring of behaviour', 'demonstration of the behaviour', and 'action planning' were rated as promising BCTs.

DISCUSSION

Specific types of BCTs might be associated with physical activity promotion or maintenance during pregnancy. More high-quality randomised controlled trials investigating the effectiveness of individual or combinations of BCTs on physical activity in pregnant women are needed.

Empirical validation of the information-motivation-behavioral skills model of gestational weight management behavior: a framework for intervention

BACKGROUND

Unhealthy gestational weight gain is a modifiable risk factor for adverse maternal and child health. Appropriate and effective intervention strategies that focus on behavioral change or maintenance are critical in weight management during pregnancy. Our aim was to uncover the influencing factors and psychosocial mechanisms of gestational weight control behavior, and to construct a behavioral model suitable for intervention based on Information-Motivation-Behavioral skills (IMB) model.

METHODS

A sample of 559 pregnant women from a municipal maternal and child healthcare facility in Jiangsu Province, China was enrolled in this cross-sectional empirical study. Partial least square structural equation modelling was used to verify the hypothesized model, and post hoc analyses was used to test the effect of parity and pre-pregnancy BMI on the model.

RESULTS

The IMB model elements can predict gestational weight management (GWM) behavior well, with information being the most influential factor. As predicted, information affects GWM directly (β = 0.325, p < 0.05) and indirectly (β = 0.054, p < 0.05) through behavioral skills. Likewise, motivation has direct (β = 0.461, p < 0.05) effects on GWM, and has indirect (β = 0.071, p < 0.05) effects through behavioral skills. Behavioral skills have a direct impact (β = 0.154, p < 0.05). The model had a goodness of fit (GOF = 0.421) and was robust when tested in subgroups of different parity or pre-pregnancy BMI.

CONCLUSION

Findings from this study supported the predictions of the IMB model for GWM behavior, and identified its modifiable determinants. The tested behavior model for GWM can serve as a new validated intervention strategy in weight management among pregnant women.

Socioecological Factors Associated With Physical Activity and Sedentary Behavior Among Workers: Using the PRECEDE-PROCEED Model

BACKGROUND

Physical inactivity is a major global health problem. Industrial automation has led to an increased number of workers who are sedentary at work. We examined whether three socioecological factors (i.e., predisposing, reinforcing, and enabling factors) derived from the PRECEDE-PROCEED model would be significantly associated with the physical activity and sedentary behavior among workers.

METHODS

A cross-sectional study was conducted among 539 employees at an electronic manufacturing plant in Gumi, South Korea. Physical activity variables of energy expenditure (MET-min/week) and sitting time at work (minutes/day) were measured by the International Physical Activity Questionnaire and the Workforce Sitting Questionnaire, respectively. Of the socioecological factors, a predisposing factor defined as self-determined motivation was measured by the Exercise Self-Regulation Questionnaire; a reinforcing factor defined as autonomy support was measured by the Work Climate Questionnaire; and an enabling factor defined as supportive workplace environment was measured by the Perceived Workplace Environment Scale.

FINDINGS

Self-determined motivation (i.e., autonomous and controlled forms of motivation), autonomy support, and a supportive workplace environment were all significantly associated with increased physical activity energy expenditure during leisure-time. However, they were not significantly associated with sitting time on working and non-working days.

CONCLUSION/APPLICATIONS TO PRACTICE

Three socioecological factors of the PRECEDE-PROCEED model were significantly associated with leisure-time physical activity among workers. Our findings may help occupational health nurses use a socioecological approach for designing effective workplace strategies to increase leisure-time physical activity among workers.

Effectiveness of the PRECEDE-PROCEED model for improving the care knowledge, skill, and sense of competence in mothers of preterm infants

Objective

This quasi-randomized controlled trial was performed to evaluate the effects of the PRECEDE-PROCEED model (PPM) in enabling mothers of preterm infants to develop care knowledge, skill, and a sense of competence.

Methods

Among 116 mothers of preterm infants, 60 received traditional discharge education (control group) and 56 received PPM discharge education (PPM group). Improvement in knowledge and skills was transformed into the mothers’ routine daily care of infants. The primary outcome was knowledge of preterm infant care. The secondary outcomes were preterm infant care skills and a sense of competence, routine intervention compliance among mothers, and the readmission rate of infants 6 months after discharge.

Results

Six months after discharge, the mean knowledge score and mean skills score were significantly higher in the PPM group than in the control group. The mothers’ sense of competence with respect to both self-efficacy and satisfaction was also significantly better in the PPM group than in the control group. Moreover, intervention behavior compliance and the readmission rate were significantly better in the PPM group than in the control group.

Conclusion

Care knowledge, skills, and sense of competence in mothers of preterm infants improved after implementation of the PPM.

A theory driven, pragmatic trial implementing changes to routine antenatal care that supports recommended pregnancy weight gain

Background

Prevention of weight gain outside recommendations is a challenge for health services, with several barriers to best practice care identified. The aim of this pragmatic implementation study with a historical control was to examine the impact of implementing a service wide education program, and antenatal care pregnancy weight gain chart combined with brief advice on women’s knowledge of recommended gestational weight gain (GWG), the advice received and actual GWG.

Methods

The PRECEDE PROCEED Model of Health Program planning guided intervention and evaluation targets and an implementation science approach facilitated service changes. Pregnant women < 22 weeks’ gestation attending the antenatal clinic at a metropolitan birthing hospital in Australia were recruited pre (2010, n = 715) and post (2016, n = 478) implementation of service changes. Weight measurements and questionnaires were completed at recruitment and 36 weeks’ gestation. Questionnaires assessed advice received from health professionals related to healthy eating, physical activity, GWG, and at recruitment only, pre-pregnancy weight and knowledge of GWG recommendations.

Results

Women who correctly reported their recommended GWG increased from 34% (pre) to 53% (post) (p < 0.001). Between pre and post implementation, the advice women received from midwives on recommended GWG was significantly improved at both recruitment- and 36-weeks’ gestation. For normal weight women there was a reduction in GWG (14.2 ± 5.3 vs 13.3 ± 4.7 kg, p = 0.04) and clinically important reduction in excess GWG between pre and post implementation (31% vs 24%, p = 0.035) which remained significant after adjustment (AOR 0.53 [95%CI 0.29–0.96]) (p = 0.005).

Conclusions

Service wide changes to routine antenatal care that address identified barriers to supporting recommended GWG are likely to improve the care and advice women receive and prevent excess GWG for normal weight women.

Cognitive Factors of Weight Management During Pregnancy Among Chinese Women: A Study Applying Protective Motivation Theory

PURPOSE

This study aimed to explore the psychological cognitive factors of weight management during pregnancy based on protective motivation theory (PMT).

DESIGN

Cross-sectional study.

SETTING

Participants were recruited at the Maternal and Child Health Hospital of Changzhou City, Jiangsu Province, China.

SAMPLE

A sample of 533 pregnant women was enrolled in the study.

MEASURES

Measures was a self-design questionnaire, comprising of demographics, cognition of weight management during pregnancy, and weight management behavior during pregnancy.

ANALYSIS

Structural equation modeling was used to examine the weight management's cognitive factors, path relationships, and the influence of maternal characteristics.

RESULTS

Self-efficacy cognition could promote gestational weight management behavior (b = .22, P < .001), but response cost cognition hindered gestational weight management (b = -.21, P < .001). Parity moderated pregnant women's self-efficacy cognition (diff b = .24, P < .01), where the self-efficacy of nullipara promoted weight management behaviors, but the self-efficacy of multipara had no significant effect. Also, the response cost factors stably existed in primipara and multipara groups, with multipara, being positively affected by response efficacy (b = .15, P < .05).

CONCLUSION

Findings highlight the need for psychological and cognitive interventions. Intervention strategies that focus on enabling women to correctly understand response cost and make an active response, improve self-efficacy cognition especially among primipara, and strengthening multipara's response efficacy among pregnant are required.

The effect of the information-motivation-behavioral skills (IMB) model variables on orthorexia nervosa behaviors of pregnant women

PURPOSE

This study aims to test the effect of the components of the Information-Motivation-Behavioral Skills Model on Orthorexia Nervosa (ON) behavior of pregnant women and health outcomes using a hypothetical model.

METHODS

The study is cross-sectional research and was carried out with 350 pregnant women who had the Non-Stress Test in the obstetrics outpatient clinic of a university hospital. The participants were selected using the convenience sampling method. The data were collected with a questionnaire. Data were analyzed using the structural equation model.

RESULTS

It was found that 26.6% of pregnant women had an ON tendency. High information for obsession with obsession with healthy eating causes more ON behaviors (β =  - 0.25, p < 0.001). The higher motivation for obsession with healthy eating obsession (β = 0.73, p < 0.01) and a higher tendency to ON behaviors (β =  - 0.16, p < 0.05) are associated with better health outcomes.

CONCLUSION

Our findings show that high levels of information and motivation about the obsession with healthy eating effect ON tendency and health outcomes. The findings are significant in that they lead and guide the interventions for the detection, prevention, and treatment of ON during pregnancy.

LEVEL OF EVIDENCE

Level V, cross-sectional study.

Bridging the Postpartum Gap: A Randomized Controlled Trial to Improve Postpartum Visit Attendance Among Low-Income Women with Limited English Proficiency

Background: Rates of postpartum visit attendance are low among all women, and particularly for low-income women. Experts in obstetrics, women's health, and health disparities are calling for novel, holistic approaches to postpartum care to better meet the needs of women and that respond to existing health care disparities. Materials and Methods: We conducted a single-site parallel-arm randomized controlled trial to determine the feasibility and effect of a co-located, co-timed 4-6 weeks postpartum obstetrics visit and well-newborn pediatric visit (i.e., "mommy-baby visit") compared with an enhanced usual postpartum visit, that is, staff scheduled the postpartum visit for the patient before hospital discharge. Results: One hundred sixteen women, of whom 76.7% (n = 89) were Latina immigrants, were enrolled postdelivery and randomized to a mommy-baby visit (n = 58, 49.5%) or to enhanced usual care (n = 58, 50.4%). Almost all study participants attended their postpartum visit (n = 109, 94.0%). There was no significant difference in postpartum visit attendance rate by randomization assignment (91.4% of mommy-baby vs. 96.6% of enhanced usual care participants). Study participants, mommy-baby intervention and enhanced usual care arms combined, were significantly more likely to attend the postpartum visit than historical controls (94.0% vs. 69.7%, respectively, p < 0.001). Conclusions: In a randomized controlled trial, we showed postpartum visit attendance rates were high for participants in both the mommy-baby and enhanced usual care arms. Postpartum visit scheduling assistance was provided to all participants and may have increased postpartum visit attendance and thereby attenuated the effect of the intervention. It is encouraging that a low-cost, low-tech, low-touch intervention, that is, postpartum appointment scheduling before hospital discharge, could increase postpartum visit attendance.

Implementation of the Living Well During Pregnancy Telecoaching Program for Women at High Risk of Excessive Gestational Weight Gain: Protocol for an Effectiveness-Implementation Hybrid Study

Background

Despite comprehensive guidelines for healthy gestational weight gain (GWG) and evidence for the efficacy of dietary counseling coupled with weight monitoring on reducing excessive GWG, reporting on the effectiveness of interventions translated into routine antenatal care is limited.

Objective

This study aims to implement and evaluate the Living Well during Pregnancy (LWdP) program in a large Australian antenatal care setting. Specifically, the LWdP program will be incorporated into usual care and delivered to a population of pregnant women at risk of excessive GWG through a dietitian-delivered telephone coaching service.

Methods

Metrics from the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework will guide the evaluation in this hybrid effectiveness-implementation study. All women aged ≥16 years without pre-exiting diabetes with a prepregnancy BMI >25 kg/m² and gaining weight above recommendations at <20 weeks’ gestation who are referred for dietetic care during the 12-month study period will be eligible for participation. The setting is a metropolitan hospital at which approximately 6% of the national births in Australia take place each year. Eligible participants will receive up to 10 telecoaching calls during their pregnancy. Primary outcomes will be service level indicators of reach, adoption, and implementation that will be compared with a retrospective control group, and secondary effectiveness outcomes will be participant-reported anthropometric and behavioral outcomes; all outcomes will be assessed pre- and postprogram completion. Additional secondary outcomes relate to the costs associated with program implementation and pregnancy outcomes gathered through routine clinical service data.

Results

Data collection of all variables was completed in December 2020, with results expected to be published by the end of 2021.

Conclusions

This study will evaluate the implementation of an evidence-based intervention into routine health service delivery and will provide the practice-based evidence needed to inform decisions about its incorporation into routine antenatal care.

Caught Between External Pressures and Internal Battles: Psychosocial Factors Affecting Gestational Weight Gain - A Scoping Review

Many physical factors (including maternal comorbidities) affecting gestational weight gain (GWG) have been widely studied; however, the psychosocial aspects pertaining to this need to be put under the microscope, especially in countries characterized by low indicators of socioeconomic development. Gaining and maintaining an adequate amount of weight during pregnancy is important to prevent premature deliveries, fetal demise, fetal macrosomia, shoulder dystocia during delivery, emergency cesarean sections, postpartum weight retention, childhood obesity, etc. A scoping review of the articles published in the last five years has revealed that perinatal outcomes like gestational weight are influenced by certain psychosocial factors, including, but not limited to, intimate partner violence, lack of social support and recognition, financial distress, household food insecurity, chronic stress and depression related to pregnancy, eating pathologies, and low self-esteem. Employing a multi-disciplinary approach, which involves seeking the help of psychiatrists/psychologists, obstetricians, nutritionists, and public health specialists, can help us mitigate undesirable outcomes related to inadequate and excessive weight gain during pregnancy. More intervention-based research focusing on psychosocial factors relating to GWG is needed in regions like South Asia, which is associated with low indicators of socioeconomic development.

Determinants of Protective Behaviors Against Endocrine Disruptors in Young Korean Women

PURPOSE

A convenience-oriented lifestyle in young people is accompanied by greater consumption of and exposure to endocrine disruptors, which can affect reproductive health, especially in women. We aimed to identify factors that influence protective behaviors against endocrine disruptors among female college students in South Korea.

METHODS

Using a cross-sectional survey design, we recruited 199 female college students. A self-administered questionnaire was used, and data were collected at the site.

RESULTS

A healthy lifestyle, information utilization, receiving peer advice on avoiding exposure to endocrine disruptors, and a history of environmental illnesses were found to be significant factors, explaining 42.0% of the variance in protective behaviors against endocrine disruptors.

CONCLUSION

Health consequences of environmental hazards and importance of maintaining a healthy lifestyle need to be emphasized in young women's healthcare. Health professionals should advocate for and empower women to protect themselves against endocrine disruptors.

Comparison of health-promoting behaviours, eating behaviour patterns and perceived social support in normal-weight and overweight pregnant women: An unmatched case-control study

Aim

The interventions based on adopting a healthy lifestyle during pregnancy have conflicting results. This study aimed to compare health-promoting, dietary patterns and social support in normal and overweight pregnant women.

Design

An unmatched case-control design was used.

Methods

A total of 360 pregnant women were selected using multistage cluster sampling and divided into two groups of normal and overweight cases. Data were collected using demographic and obstetrics characteristics, health-promoting lifestyle, perceived social support and eating behaviour questionnaires.

Results

The evaluation of the health-promoting behaviours and dietary patterns demonstrated a significant difference between the mean of total scores and their subdomains including self-actualization, nutrition, consumption of healthy and low-fat foods, fast food and sweets, as well as emotional eating and accidental planning. There was no significant difference between the two groups about social support.

Attendance rates and characteristics of women with obesity referred to the dietitian for individual weight management advice during pregnancy

BACKGROUND

Engagement in services to support healthy weight management during pregnancy is poor. A better understanding of those who attend is important in supporting women to participate in preventative health services.

AIMS

This retrospective observational study aimed to report attendance rates of pregnant women with obesity (body mass index (BMI) ≥ 30 kg/m² ) referred to a dietitian between 2012 and 2018 for weight management and describe who was referred and attended.

MATERIALS AND METHODS

Demographic, attendance and medical data for women with obesity who were either referred to a dietitian or were not referred were sourced from hospital data. Chi-squared and t-tests were used to compare groups. Binary logistic regression analysis was used to identify characteristics associated with attendance within the referred group.

RESULTS

Of 5426 eligible women, 523 were referred to the dietitian, and 4903 women were not referred (Total sample: 29 ± 6 years, 39.0 ± 2.1 weeks gestation at birth). Referred women self-reported a 6.7 kg/m² higher pre-pregnancy BMI, 7% more were subsequently diagnosed with gestational diabetes mellitus (GDM), and 9% more were induced (P < 0.001) indicating a higher risk of adverse outcomes. Referred women attended a median (range) of 2 (0-8) appointments. The majority (78%) attended ≥1 appointment, and 41% attended ≥3 appointments. Women referred by a midwife (65%) or diagnosed with GDM were 1.9 and 3.0 times more likely to attend, respectively (P < 0.01). Being a smoker was negatively associated with attendance (odds ratio 0.388, P < 0.001).

CONCLUSIONS

Pregnant women with obesity referred for dietetic weight management appear at higher risk of adverse outcomes, with most attending ≥1 appointment. Engaging midwives in promoting referrals may increase attendance.

Change of the Patient’s Life Style as a Target for Psychological Rehabilitation: Organization of Rehabilitation as an Interpersonal Activity on Personal and Interpersonal Levels

Development of health behavior in patients is an important task of psychological rehabilitation. The models of behavior change and their application in psychological rehabilitation are analyzed. We discuss applications of the PROCEED–PROCEED model to the evaluation of rehabilitation. The value of the model is in the possibility to operationalize and formalize assessment of the effectiveness of the organization of rehabilitation. Based on interdependence theory the importance of achieving consistency of rehabilitation goals and the gradual transformation of expectations is discussed. The effectiveness of rehabilitation and the possibility of patient's behavior change at early stage are associated with the formation of interpersonal relationships that are consistent with the expectations of the patient and his family. The lifestyle changes and active participation of the patient in rehabilitation can only be provided by the transformation of one’s relations with specialists. Subsequently, this interaction has to be reconstructed in the direction of greater participation and responsibility of the patient.

Associations between pre-pregnancy BMI, gestational weight gain, and prenatal diet quality in a national sample

This secondary analysis explored the association between gestational weight gain, pre-pregnancy body mass index (BMI), and prenatal diet quality in a United States national sample. The sample comprised 1322 pregnant women in the longitudinal Infant Feeding Practices Study II with Diet History Questionnaire data. Diet quality in the third trimester was assessed using the Alternative Healthy Eating Index for Pregnancy. Self-reported pre-pregnancy BMI (categorized as underweight<18.5, normal weight 18.5–24.9, overweight 25.0–29.9, and obese≥30.0) and total gestational weight gain were used to categorize adherence to the Institute of Medicine’s recommendations as inadequate, adequate, or excessive weight gain. Diet quality in pre-pregnancy BMI and gestational weight gain groups were compared using Tukey-adjusted generalized linear models adjusted for sociodemographic factors, Women, Infants, and Children participation, parity, and energy intake. Due to missing gestational weight gain data, sensitivity analyses with multiply imputed data were conducted. Women were on average 28.9 years old and of higher socioeconomic status (40% college graduates) and mostly non-Hispanic White (84%), and the mean Alternative Healthy Eating Index for Pregnancy score was 61.2 (of 130). Both pre-pregnancy BMI and gestational weight gain were inversely associated with diet quality scores (p<0.01). The interaction between pre-pregnancy BMI and gestational weight gain was significant (p = 0.04), therefore gestational weight gain models were stratified by BMI group. In stratified adjusted models, gestational weight gain was differently associated with diet quality scores (p<0.05) among women with underweight, normal weight, overweight, and obesity. The relationship between gestational weight gain and prenatal diet quality depended on pre-pregnancy BMI. For example, within women with normal weight, higher diet quality was observed in the adequate gestational weight gain group. Interventions to broadly improve prenatal diet quality are needed, however, resources can be used to target women with higher pre-pregnancy BMIs and women with inadequate or excessive gestational weight gain.

A mixed method study evaluating the integration of pregnancy weight gain charts into antenatal care

Monitoring pregnancy weight can reduce excess gestational weight gain (GWG), and is recommended in clinical practice guidelines as part of routine care. This study aimed to evaluate the implementation of routine weight monitoring using a pregnancy weight gain chart (PWGC), and assess health care professionals (HCPs) and pregnant women's attitudes and practices around its use. A semiquantitative survey was conducted with a consecutive sample of antenatal women at 16 and 36 weeks gestation. Women were weighed, and a PWGC audit done at 36 weeks gestation to assess adherence to chart use and GWG. A cross-sectional survey of antenatal HCPs at the Australian facility assessed staff attitudes and practices relating to weight monitoring and PWGC use. Of the 291 women surveyed, 68% reported being given a PWGC. Of the audited PWGCs (n = 258), 54% had less than three weights recorded, 36% had errors, and 3% were unused. All HCPs surveyed (n = 42) were aware of the PWGC, 63% reported using it to track GWG regularly and 26% believed it to be only the woman's responsibility (i.e., not the midwife's role) to complete it. Seventy-six percent reported they needed more training in counselling pregnant women, and insufficient time was a main barrier to weighing and conversing with women. It is feasible to implement a PWGC into routine antenatal care. Clarity over women's and HCPs responsibility for monitoring GWG and completion of the PWGC is needed. Training on correct PWGC use and counselling and workforce engagement are required to overcome barriers and support healthy GWG.

Using formative research with older adults to inform a community physical activity programme: Get Healthy, Get Active

Aim

The purpose of this formative study was to explore current knowledge and attitudes towards physical activity, as well as perceived barriers, facilitators and opportunities for physical activity participation among older adults living in the community. The findings have subsequently informed the design, delivery and recruitment strategies of a local community physical activity intervention programme which forms part of Sport England’s national Get Healthy, Get Active initiative.

Background

There is a growing public health concern regarding the amount of time spent in sedentary and physical activity behaviours within the older adult population.

Methods

Between March and June 2016, 34 participants took part in one of six focus groups as part of a descriptive formative study. A homogenous purposive sample of 28 community dwelling white, British older adults (six male), aged 65–90 years (M=78, SD=7 years) participated in one of five focus group sessions. An additional convenience pragmatic sub-sample of six participants (three male), aged 65–90 years (M=75, SD=4 years), recruited from an assisted living retirement home participated in a sixth focus group. Questions for focus groups were structured around the PRECEDE stage of the PRECEDE–PROCEDE model of health programme design, implementation and evaluation. Questions addressed knowledge, attitudes and beliefs towards physical activity, as well as views on barriers and opportunities for physical activity participation. All data were transcribed verbatim. Thematic analysis was then conducted with outcomes represented as pen profiles.

Findings

Consistent views regarding both the potential physical and psychosocial benefits of physical activity were noted regardless of living status. The themes of, opportunities and awareness for physical activity participation, cost, transport, location and season/weather varied between participants living in an assisted living retirement home and community dwelling older adults. Further comparative research on the physical activity requirements of older adults living in assisted living versus community settings are warranted.

Prospective Relationships between Health Cognitions and Excess Gestational Weight Gain in a Cohort of Healthy and Overweight Pregnant Women

BACKGROUND

Excess gestational weight gain (GWG) contributes to long-term obesity in mothers and children. To guide the tailoring of interventions to prevent excess GWG, a better understanding is needed of the lifestyle-related health cognitions that influence women's attempts to manage GWG.

OBJECTIVE

To examine the relationship between health cognitions and excess GWG for women who enter pregnancy at a healthy weight (body mass index <25) or overweight (body mass index ≥25). It was hypothesized that health cognitions with a positive (negative) influence on health behavior would be associated with lower (higher) likelihood of excess GWG and that specific associations would differ between weight status groups.

DESIGN

This prospective, observational study commenced when participants were <20 weeks' gestation, continuing until the end of their pregnancy. A self-administered quantitative survey at recruitment assessed prepregnancy weight and lifestyle-related health cognitions. Height was measured at 16 weeks and weight at 36 weeks using standard procedures.

PARTICIPANTS AND SETTING

A consecutive sample of pregnant women (n=715) were recruited from an Australian metropolitan hospital between August 2010 and January 2011. All women <20 weeks' gestation were eligible unless they had preexisting type 1 or 2 diabetes or insufficient English language skills to complete questionnaires.

MAIN OUTCOME MEASURES

Excess GWG defined according to Institute of Medicine 2009 recommendations and predisposing, reinforcing, and enabling cognitions for lifestyle health behaviors.

STATISTICAL ANALYSES PERFORMED

Logistic regression analyses examined associations between health cognitions and excess GWG stratified for prepregnancy weight status.

RESULTS

For healthy-weight women, higher weight locus of control scores were protective against excess GWG (odds ratio 0.6, 95% CI 0.4 to 0.8), whereas higher perceived risk scores (personal risk and risk arising from prepregnancy weight) (odds ratio 1.3, 95% CI 1.1 to 1.7) were associated with excess GWG. For overweight women higher negative outcome expectation scores were associated with an increased risk of excess GWG (odds ratio 1.4, 95% CI 1.1 to 2.0).

CONCLUSIONS

Lifestyle-related health cognitions are associated with excess GWG and differed by prepregnancy weight status, suggesting the need to tailor behavior change interventions accordingly.
