Prenatal weight gain: who is counseled?

Antenatal care addressing gestational weight gain (GWG): a cross sectional study of pregnant women's reported receipt and acceptability of recommended GWG care and associated characteristics

BACKGROUND

The Australian Clinical Practice Guidelines for Pregnancy Care recommend that during the first and subsequent antenatal visits all pregnant women are weighed; advised of recommended gestational weight gain (GWG), dietary intake and physical activity; and offered referrals for additional support if needed. The extent to which these recommendations are implemented and women's acceptability of recommended care is unknown. This study examines women's reported receipt and acceptability of guideline care for GWG, and characteristics associated with receipt of such care and its acceptability.

METHODS

From September 2018 to February 2019 a telephone survey was undertaken with women who had recently had a baby and received antenatal care from five public maternity services within a health district in Australia. Women self-reported their demographic characteristics, and receipt and acceptability of recommended GWG care. Receipt and acceptability of such care, and their association with the characteristics of women and the maternity service they attended, were examined using descriptive statistics and multivariable logistic regression analyses.

RESULTS

Of 514 women, 13.1% (95%CI:10.3-16.5) reported that they received an assessment of weight at both their first and a subsequent antenatal visit, and less than one third (30.0%; 95%CI:26.0-33.9) received advice on their recommended GWG range, dietary intake and physical activity. Just 6.6% (95%CI:4.8-9.1) of women reported receiving all assessment and advice components of recommended antenatal care, and 9.9% (95%CI:7.6-12.8) of women reported being referred for extra support. Women who were younger (OR = 1.13;95%CI:1.05-1.21), identifying as Aboriginal and Torres Strait Islander (OR = 24.54;95%CI:4.98-120.94), had a higher pre-pregnancy BMI (OR = 1.13;95%CI:1.05-1.21), were experiencing their first pregnancy (OR = 3.36;95%CI:1.27-8.86), and lived in a least disadvantaged area (compared to mid-disadvantaged area (OR = 18.5;95%CI:2.6-130.5) and most disadvantaged area (OR = 13.1;95%CI:2.09-82.4)) were more likely to receive recommended assessment and advice. Most Aboriginal (92%) and non-Aboriginal (93%) women agreed that recommended GWG care is acceptable.

CONCLUSION

Most women perceive antenatal care for GWG as recommended by the Clinical Practice Guidelines as acceptable, but did not receive it. When provided, such care is not delivered consistently to all women regardless of their characteristics or those of the maternity service they attend. There is a need for service-wide practice change to increase routine GWG care in pregnancy for all women.

Association Between Maternal Body Mass and Physical Activity Counseling During Pregnancy

Aims: The antenatal period provides an important opportunity for giving advice on healthy lifestyle choices. However, the prevalence of maternal obesity is increasing, and women report that they do not receive counseling. We investigated the information given to pregnant women on gestational weight gain, physical activity, and nutrition during pregnancy in relation with their initial weight status, current gestational weight gain and diagnoses of either pre-pregnancy overweight/obesity or excessive gestational weight gain. Methods: Cross-sectional survey using a questionnaire. Pregnant participants (n = 141) were recruited from a midwife center. They completed a structured questionnaire on the information they received during their pregnancy and we assessed its relationship with their weight. Results: We found that many pregnant women did not receive advice about physical activity, gestational weight gain and nutrition (37.5, 53.2, and 66.2%, respectively). Women with weight problems (pre-pregnancy overweight/obesity and excessive gestational weight gain) were less targeted for counseling, although more than 80% of the women viewed receiving information on these topics as positive. Also, being informed of a weight problem was associated with a greater chance of receiving information about physical activity, gestational weight gain and nutrition (all p < 0.05). However, verbalization of the weight problems was low (14.0% of women with pre-pregnancy overweight were informed of their status). Conclusion: Health professionals should dispense more information, especially on PA and particularly for women with weight problems. Verbalization of the weight problem seems associated with more frequent transmission of information.

Delivering Coordinated Cardio-Obstetric Care from Preconception through Postpartum

Coordinated preconception through postpartum cardio-obstetrics care is necessary to optimize both maternal and fetal health. Maternal mortality in the United States is increasing, largely driven by increasing cardiovascular (CV) disease burden during pregnancy and needs to be addressed emergently. Both for women with congenital and acquired heart disease, CV complications during pregnancy are associated with increased future risk of CV disease. Comprehensive cardio-obstetrics care is a powerful way of ensuring that women's CV risks before and during pregnancy are appropriately identified and treated and that they remain engaged in CV care long term to prevent future CV complications.

A Qualitative Study of Motivators, Strategies, Barriers, and Learning Needs Related to Healthy Cooking during Pregnancy

Nutrition during pregnancy has lifelong impacts on the health of mother and child. However, this life stage presents unique challenges to healthy cooking and eating. Cooking interventions show promising results, but often lack theoretical basis and rigorous evaluation. The objective of this formative, qualitative study was to explore motivators, strategies, and barriers related to healthy cooking during pregnancy. Pregnant individuals’ preferences for a cooking education program were also explored. We conducted five focus groups with pregnant individuals (n = 20) in Southeast Michigan in 2019. Focus groups were audio-recorded and transcribed verbatim, then double coded by two members of the research team. Mean gestational age was 18.3 ± 9.6 weeks. Common motivators included feeding other children, avoiding pregnancy complications, promoting fetal growth, and avoiding foodborne illness. Challenges included pregnancy symptoms, navigating nutrition recommendations, mental energy of meal planning, family preferences, and time constraints. Strategies employed were meal planning and including a variety of foods. Participants identified organizational strategies, recipes, nutrition information, and peer support as important components of a cooking intervention during pregnancy. This study characterized multiple challenges to healthy home cooking during pregnancy, providing novel insight to inform the development of cooking skills education programs during this important life stage.

Comparison and Characterization of Prenatal Nutrition Counseling among Large-for-Gestational Age Deliveries by Pre-Pregnancy BMI

It is recommended that prenatal care include nutrition counseling; however, <70% of women report receipt of nutrition counseling during pregnancy. In this study, we aimed to characterize prenatal nutrition counseling (PNC) among large-for-gestational age deliveries at a low-income and minority-serving hospital by performing a retrospective chart review of infants with a birth weight > 4000 g. Of the 2380 deliveries, 165 met the inclusion criteria. Demographics, PNC receipt, and pregnancy outcomes were compared among normal-weight (NW; BMI: 18.5–24.9 kg/m², 19%, n = 31), overweight (OW; BMI: 25–29.9 kg/m², 29%, n = 48), and obese (OB; BMI > 30 kg/m², 52%, n = 86) women. The majority (78%, n = 129) of women were Hispanic White with a mean age of 30.4 ± 5.7 yrs and gestational weight gain of 12.1 ± 5.8 kgs. A total of 62% (n = 103) of women received PNC. A total of 57% gained above the Institute of Medicine (IOM) recommendations (n = 94). OB women were 2.6 and 2.1 times more likely to receive PNC than OW (95% CI: 1.1–2.0) and NW (95% CI: 0.9–1.9) women, respectively. Women who gained within the IOM recommendations for their pre-pregnancy body mass index (BMI) were 50% less likely to receive PNC than women who gained above the IOM recommendations for their pre-pregnancy weight (χ = 4.45, p = 0.035; OR = 0.48, CI: 0.24 to 0.95). Infant birthweight was significantly higher among women who received PNC (4314 ± 285 vs. 4197 ± 175 g, p = 0.004). These data suggest that PNC was directed toward women who enter pregnancy in the obese weight category and/or gain excessively across gestation. Future studies should provide PNC to all women to evaluate whether it reduces the risk of delivering large-for-gestational age deliveries across all maternal weight categories. Additionally, more work is needed to identify the types of PNC that are most effective for this high-risk population.

Provider advice on physical activity and nutrition in twin pregnancies: a cross-sectional electronic survey

BACKGROUND

Health care providers should counsel pregnant patients on physical activity and nutrition to improve pregnancy outcomes. However, little is known about provider advice on these lifestyle behaviors among women pregnant with twins, a growing population at high risk for pregnancy complications. We examined the prevalence and content of provider advice on physical activity and nutrition among women pregnant with twins.

METHODS

A cross-sectional electronic survey was administered to 276 women who delivered twins in the past 3 years and received prenatal care in the United States. The proportion of women reporting provider advice on physical activity and nutrition during prenatal visits (yes/no) was assessed and open-ended questions examined the content of provider advice. Bivariate differences in participant characteristics, stratified by provider advice on physical activity and nutrition (yes/no), were assessed. Responses from open-ended questions were examined using a content analysis approach to identify commonly reported advice on physical activity and nutrition.

RESULTS

Approximately 75 and 63% of women reported provider advice on physical activity and nutrition, respectively, during their twin pregnancy. Women who recalled advice on physical activity most commonly reported recommendations to walk at a light to moderate intensity level. However, few women reported physical activity recommendations consistent with current guidelines, and approximately 55% of women reported provider advice to limit or restrict activity during their pregnancy, including bedrest. Nutrition advice was focused on eating a healthy, balanced diet and increasing protein intake. More women reported self-initiating the conversation on physical activity with their provider (40%) compared to nutrition (21%). Despite limited advice, 70% of women reported being satisfied or very satisfied with the information they received from their provider on physical activity or nutrition.

CONCLUSIONS

The majority of women reported provider advice on physical activity and nutrition during their twin pregnancies. However, advice was limited in detail, and physical activity levels were commonly restricted, despite the lack of evidence that activity restriction is beneficial during pregnancy. More research is needed to determine the optimal physical activity and dietary patterns in twin pregnancies to facilitate clear and consistent provider counseling on these lifestyle behaviors.

Targeting obstetric providers in interventions for obesity and gestational weight gain: A systematic review

Background

Providers need to be comfortable addressing obesity and gestational weight gain so they may give appropriate care; however, health care providers lack guidelines for the most effective educational strategies to assist in providing optimal care.

Objective

To identify studies that involved the obstetric provider in interventions for either the perinatal management of obesity and/or gestational weight gain in a systematic review.

Search strategy

A keyword search of databases was performed up to April 2017.

Selection criteria

Obstetric providers who participated in an intervention with the aim to change a provider’s clinical practice, knowledge, and/or satisfaction with the intervention in relation to the perinatal management of obesity or gestational weight gain were included. Provider intervention could include training or education, changes in systems or organization of care, or resources to support practice. PROSPERO database #42016038921.

Data collection and analysis

Bias was assessed according to the validated Mixed Methods Appraisal Tool. The following variables were synthesized: study location and setting, provider and patient characteristics, intervention features, outcomes and efficacy, and strengths and weakness.

Main results

Of the 6,821 abstracts screened, seven studies (4 quantitative, 3 mixed-methods) with a total of 335 providers met the inclusion criteria; two of which focused on the management of obesity, three focused on gestational weight gain, and two focused on both topics. Interventions that incorporated motivational interviewing skills (n = 2), required additional training for the research study and addressed specific knowledge deficits such as nutrition and exercise (n = 3), and interfaced with the electronic medical record (n = 1) demonstrated the greatest impact on provider outcomes. Provider reported satisfaction scores were generally favorable, but none addressed provider-level efficacy in practice change.

Conclusions

Given the limited number of studies, varying range of provider participation, and lack of provider-level efficacy, further evaluation of provider training and involvement in interventions for perinatal obesity or gestational weight gain is indicated to determine best practices for provider and patient outcomes.

Exercise During Pregnancy: Obstetricians' Beliefs and Recommendations Compared to American Congress of Obstetricians and Gynecologists' 2015 Guidelines

Purpose Obesity and excessive weight gain during pregnancy is a growing problem, conferring severe health risks for both mother and fetus. Exercise can help combat this epidemic. However, many pregnant women are not meeting the American Congress of Obstetricians and Gynecologists' (ACOG's) 2015 guidelines for exercise during pregnancy. The objective of this study was to evaluate obstetricians' beliefs and recommendations regarding exercise during pregnancy compared to ACOG's 2015 recommendations. Method Obstetricians were recruited via three different forums to complete a twenty-question survey: at a regional conference for Alabama and Mississippi ACOG members, at the University of Alabama at Birmingham's Obstetrics and Gynecology Department's Grand Rounds, and via telephone. Univariate statistical analysis was conducted with RedCap. Results  Seventy-one surveys were completed: 33 from the ACOG conference, 27 from Grand Rounds, and 11 from those recruited by telephone. Eighty-eight percent (n=60) of respondents correctly identified ACOG's recommendation of unrestricted exercise for women with uncomplicated pregnancies. One-fourth (24%; n=16) regularly discuss exercise with most (76%-100%) pregnant patients. Most (57%; n=59) do not consistently ("never," "rarely," or "sometimes") recommend sedentary patients begin exercising during pregnancy. Nearly all (97%; n=66) advise first-trimester patients to perform aerobic exercise two to five days per week, but the recommended duration varies. One-fourth (24%; n=16) do not recommend strength-training exercise during the first trimester. Twenty-five percent (n=17) and 32% (n=22) recommend decreased aerobic or strength-training exercise, respectively, in the third trimester. More than half (54%; n=37) recommend pregnant patients limit exercise by heart rate, most commonly 121-140 bpm (25%; n=17) or 141-160 bpm (24%; n=16). Sixty-eight percent (n=46) feel "comfortable" or "very comfortable" providing advice on exercise during pregnancy. Conclusion Despite believing exercise benefits pregnant women, knowing ACOG's 2015 guidelines endorse unrestricted exercise for women with uncomplicated pregnancies, and feeling comfortable discussing this topic with patients, obstetricians are not consistently counseling their pregnant patients on exercise. Notably, physicians are not instructing their sedentary pregnant patients to exercise. While most physicians provide appropriate advice on aerobic exercise, their advice on resistance training, maximum heart rate during exercise and third-trimester exercise are often discordant with ACOG's guidelines.

Achieving Appropriate Gestational Weight Gain: The Role of Healthcare Provider Advice

BACKGROUND

The Institute of Medicine (IOM) revised gestational weight gain recommendations in 2009. We examined associations between healthcare provider advice about gestational weight gain and inadequate or excessive weight gain, stratified by prepregnancy body mass index category.

MATERIALS AND METHODS

We analyzed cross-sectional data from women delivering full-term (37-42 weeks of gestation), singleton infants from four states that participated in the 2010-2011 Pregnancy Risk Assessment Monitoring System (unweighted n = 7125). Women reported the weight gain range (start and end values) advised by their healthcare provider; advice was categorized as follows: starting below recommendations, starting and ending within recommendations (IOM consistent), ending above recommendations, not remembered, or not received. We examined associations between healthcare provider advice and inadequate or excessive, compared with appropriate, gestational weight gain using adjusted prevalence ratios (aPR) and 95% confidence intervals (CIs).

RESULTS

Overall, 26.3% of women reported receiving IOM-consistent healthcare provider advice; 26.0% received no advice. Compared with IOM-consistent advice, advice below recommendations was associated with higher likelihood of inadequate weight gain among underweight (aPR 2.22, CI 1.29-3.82) and normal weight women (aPR 1.57, CI 1.23-2.02); advice above recommendations was associated with higher likelihood of excessive weight gain among all but underweight women (aPR range 1.36, CI 1.08-1.72 to aPR 1.42, CI 1.19-1.71). Not remembering or not receiving advice was associated with both inadequate and excessive weight gain.

CONCLUSIONS

Few women reported receiving IOM-consistent advice; not receiving IOM-consistent advice put women at-risk for weight gain outside recommendations. Strategies that raise awareness of IOM recommendations and address barriers to providing advice are needed.

Provider Advice and Women's Intentions to Meet Weight Gain, Physical Activity, and Nutrition Guidelines During Pregnancy

OBJECTIVES

To determine the prevalence and accuracy of patient-reported provider advice on weight gain, physical activity, and nutrition during prenatal visits and to examine the associations of provider advice with women's behavioral intentions toward weight gain, physical activity, and nutrition.

METHODS

A mixed-methods study design was used to assess patient-report of provider advice and health intentions in women between 20 and 30 weeks gestation (n = 188). Bivariate analyses examined patient-reported provider advice on weight gain, physical activity, and nutrition with women's behavioral intentions. Linear and logistic regression models examined associations of provider weight gain recommendations with women's intended weight gain.

RESULTS

Approximately 52 % of women reported provider advice on weight gain, 63 % on physical activity, and 56 % on nutrition. Of those who reported weight gain advice, 79 % cited provider recommendations within the Institute of Medicine guidelines, 9 % below, and 11 % above. Patient-report of provider advice on physical activity and nutrition were consistent with guidelines, but limited in scope. Provider advice (yes/no) was significantly associated with women's intentions to meet physical activity (p = 0.01) and nutrition (p = 0.02), but not weight gain guidelines (p = 0.86). Provider recommended weight gain (pounds) was significantly associated with women's intended weight gain in linear and logistic regression models.

CONCLUSIONS FOR PRACTICE

A large percentage of women report receiving no advice from providers on weight gain, physical activity or nutrition during pregnancy. Of those who receive advice, most report recommendations consistent with current guidelines. Provider advice was associated with women's weight gain, physical activity, and nutrition intentions in pregnancy.

Patient-Provider Communication and Counseling about Gestational Weight Gain and Physical Activity: A Qualitative Study of the Perceptions and Experiences of Latinas Pregnant with their First Child

Latina women in the United States (U.S.) are disproportionately affected by obesity and are more likely to begin pregnancy overweight and gain excessive weight during pregnancy. The prenatal care period represents a window of opportunity for women to access the healthcare system and receive preventive services, education, nutritional support, and other social services to improve pregnancy outcomes. Excessive gestational weight gain (GWG) has numerous negative short- and long-term consequences for both the mother and newborn. We explored nulliparous Latina women's perceptions about their experiences communicating with their primary healthcare provider about GWG and physical activity (PA) to identify possible intervention targets using in-depth, semi-structured interviews. Bilingual, trained research staff conducted 23 interviews with first-time pregnant Latinas between 22 and 36 weeks of gestation. Interviews were transcribed verbatim and analyzed using content analysis. Salient text passages were extracted, shortened, coded, and grouped into categories. Women, including those who self-identified as being overweight or obese prior to pregnancy, reported receiving limited or no advice from their healthcare providers about GWG or PA. Additionally, analysis revealed that although participants value information received from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) program counselors, they would like to receive more information from their primary healthcare providers about adequate GWG. Furthermore, study findings indicate that some participants received conflicting information regarding PA during pregnancy. Study findings suggest the need for increased integration of communication and counseling about GWG and PA into prenatal care services to promote healthy weight gain and PA among low-income Latina women.

Clinician self-efficacy in initiating discussions about gestational weight gain

OBJECTIVE

To compare prenatal care providers' perceived self-efficacy in starting discussions about gestational weight gain with pregnant women under a variety of conditions of gradated difficulty, when weight gain has been in excess of current guidelines.

DESIGN

A 42-item online questionnaire related to the known barriers to and facilitators of having discussions about gestational weight gain.

SETTING

Canada.

PARTICIPANTS

Prenatal care providers were contacted through the Family Medicine Maternity Care list server of the College of Family Physicians of Canada.

MAIN OUTCOME MEASURES

The 42 items were clustered into categories representing patient factors, interpersonal factors, and system factors. Participants scored their self-efficacy on a scale from 0 ("cannot do at all") to 5 ("moderately certain can do") to 10 ("highly certain can do"). The significance level was set at α = .05.

RESULTS

Overall, clinicians rated their self-efficacy to be high, ranging from a low mean (SD) score of 5.14 (3.24) if the clinic was running late, to a high mean score of 8.97 (1.34) if the clinician could externalize the reason for undertaking the discussion. There were significant differences in self-efficacy scores within categories depending on the degree of difficulty proposed by the items in those categories.

CONCLUSION

The results were inconsistent with previous studies that have demonstrated that prenatal care providers do not frequently raise the subject of excess gestational weight gain. On the one hand providers rate their self-efficacy in having these discussions to be high, but on the other hand they do not undertake the behaviour, at least according to their patients. Future research should explore this discrepancy with a view to informing interventions to help providers and patients in their efforts to address excess gestational weight gain, which is increasingly an important contributor to the obesity epidemic.

Where Do Women Get Advice About Weight, Eating, and Physical Activity During Pregnancy?

BACKGROUND

Most women report not receiving information about gestational weight gain (GWG) from prenatal providers, but less is known about other sources of information and their potential impacts on GWG. The purpose of this study was to investigate sources of information about diet, physical activity, and weight control during pregnancy, and the impact of information sources on maternal GWG.

MATERIALS AND METHODS

Participants were 183 women with normal weight and 172 women with overweight/obesity who had enrolled in a prenatal lifestyle intervention trial. At 6 weeks postpartum, women were asked whether they had received information about "diet, physical activity, or weight control" from 12 sources uninvolved in the trial (e.g., physician, Internet, and friend) and, if received, the extent to which they followed the advice. Information sources were examined in relation to odds of exceeding Institute of Medicine (IOM) GWG guidelines based on measured weights.

RESULTS

Most women reported receiving information from a book (60.6%) or the Internet (58.3%). Advice from physicians, dietitians, or nurses was reported in 55.6%, 48.2%, and 33.9% of women, respectively. Reported receipt of information from physicians was associated with reduced Odds Ratio ([95% Confidence Interval] = 0.55 [0.35-0.88]; p = 0.01) of exceeding IOM GWG guidelines. Reported receipt of information from other sources was not related to GWG.

CONCLUSIONS

Books and the Internet were the most prevalent information sources reported for prenatal diet, physical activity, and weight control. However, of all sources, only physician provision of information was associated with reduced odds of excessive GWG.

Women's perceptions of discussions about gestational weight gain with health care providers during pregnancy and postpartum: a qualitative study

Background

Maternal body weight is an indicator of the health of a mother and her developing fetus. Risks of poor maternal and fetal health issues increase when women gain too little or too much weight during pregnancy. A study of 600 women from Alberta, Canada, reported approximately 30, 46, 80, and 80% of underweight, healthy weight, overweight, and obese women, respectively, gained in excess of Health Canada gestational weight gain guidelines. Behavioural interventions during pregnancy have shown to be effective at supporting women achieve gestational weight gain (GWG) recommendations and return to their pre-pregnancy weight postpartum, yet few women are counseled about weight gain during pregnancy. A discrepancy exists between health care providers’ (HCP) reported counseling behaviours and women’s perceptions of counseling by HCPs; most HCPs report counseling women about GWG; conversely, most women report not receiving counseling about GWG. This study explored women’s experiences with GWG and their perceptions of discussions about GWG with HCPs during pregnancy and postpartum. This will help to identify gaps in service delivery and highlight areas for improvement that may better support women to achieve GWG recommendations leading to better health outcomes for women and children.

Methods

Five focus groups (n = 26) were conducted with women up to 1 year postpartum across the five Alberta health zones. Focus groups were transcribed verbatim and analyzed using qualitative content analysis.

Results

GWG is important to women, for their health and for the health of their baby. In-depth conversations with HCPs about GWG or weight loss do not occur; however, women want the opportunity to discuss weight gain/loss with HCPs. Women would like discussions about gestational weight gain/loss to become part of standard care and offered to all women.

Conclusions

Women suggested that discussions about GWG should occur with all women, and that HCPs should initiate these discussions by asking women how they feel about discussing weight. Conversations should begin early on in pregnancy and continue through to the postpartum period. Interventions assessing discussions about GWG should be implemented and evaluated as this has been identified as a gap in prenatal service delivery.

Come On! Using intervention mapping to help healthy pregnant women achieve healthy weight gain

OBJECTIVE

Gaining too much or too little weight in pregnancy (according to Institute of Medicine (IOM) guidelines) negatively affects both mother and child, but many women find it difficult to manage their gestational weight gain (GWG). Here we describe the use of the intervention mapping protocol to design 'Come On!', an intervention to promote adequate GWG among healthy pregnant women.

DESIGN

We used the six steps of intervention mapping: (i) needs assessment; (ii) formulation of change objectives; (iii) selection of theory-based methods and practical strategies; (iv) development of the intervention programme; (v) development of an adoption and implementation plan; and (vi) development of an evaluation plan. A consortium of users and related professionals guided the process of development.

RESULTS

As a result of the needs assessment, two goals for the intervention were formulated: (i) helping healthy pregnant women to stay within the IOM guidelines for GWG; and (ii) getting midwives to adequately support the efforts of healthy pregnant women to gain weight within the IOM guidelines. To reach these goals, change objectives and determinants influencing the change objectives were formulated. Theories used were the Transtheoretical Model, Social Cognitive Theory and the Elaboration Likelihood Model. Practical strategies to use the theories were the foundation for the development of 'Come On!', a comprehensive programme that included a tailored Internet programme for pregnant women, training for midwives, an information card for midwives, and a scheduled discussion between the midwife and the pregnant woman during pregnancy. The programme was pre-tested and evaluated in an effect study.

Effects of Group Prenatal Care on Food Insecurity during Late Pregnancy and Early Postpartum

OBJECTIVE

This study compared the effects of group to individual prenatal care in late pregnancy and early postpartum on (1) women's food security and (2) psychosocial outcomes among food-insecure women.

METHODS AND RESULTS

We recruited 248 racially diverse, low-income, pregnant women receiving CenteringPregnancy™ group prenatal care (N = 124) or individual prenatal care (N = 124) to complete surveys in early pregnancy, late pregnancy, and early postpartum, with 84 % completing three surveys. Twenty-six percent of group and 31 % of individual care participants reported food insecurity in early pregnancy (p = 0.493). In multiple logistic regression models, women choosing group versus individual care were more likely to report food security in late pregnancy (0.85 vs. 0.66 average predicted probability, p < 0.001) and postpartum (0.89 vs. 0.78 average predicted probability, p = 0.049). Among initially food-insecure women, group participants were more likely to become food-secure in late pregnancy (0.67 vs. 0.35 individual care average predicted probability, p < 0.001) and postpartum (0.76 vs. 0.57 individual care average predicted probability, p = 0.052) in intention-to-treat models. Group participants were more likely to change perceptions on affording healthy foods and stretching food resources. Group compared to individual care participants with early pregnancy food insecurity demonstrated higher maternal-infant attachment scale scores (89.8 vs. 86.2 points for individual care, p = 0.032).

CONCLUSIONS

Group prenatal care provides health education and the opportunity for women to share experiences and knowledge, which may improve food security through increasing confidence and skills in managing household food resources. Health sector interventions can complement food assistance programs in addressing food insecurity during pregnancy.

Obesity in Pregnancy: A Qualitative Approach to Inform an Intervention for Patients and Providers

To investigate perceptions of minority pregnant women and providers about obesity and gestational weight gain (GWG), and to explore strategies to improve management of obesity in pregnancy with an emphasis on group prenatal care. Sixteen primarily non-Hispanic black pregnant women with a body mass index ≥ 30 kg/m(2) and 19 prenatal care providers participated in focus groups. Discussion topics included GWG goals, body image, health behaviors, and group prenatal care with additional emphasis on provider training needs. Women frequently stated a GWG goal >20 lbs. Women described a body image not in line with clinical recommendations ("200 pounds is not that big."). They avoided the term "obese". They were interested in learning about nutrition and culturally-acceptable healthy cooking. Women would enjoy massage and exercise in group settings, though definitions of "exercise" varied. Family members could help, but generational differences posed challenges. Most had to "encourage myself" and "do this for me and the baby". Providers expressed discomfort discussing GWG and difficulty finding the right words for obesity, which was partially attributed to their own weight. They noted the challenges they faced during prenatal care including time constraints, cultural myths, and system issues. Providers considered a group setting with social support an ideal environment to address health behaviors in obese women. Culturally-tailored programs that use acceptable terms for obesity, provide education regarding healthy eating and safe exercise, and encourage support from social networks may be effective in addressing GWG in obese minority women. Provider training in communication skills is necessary to address obesity in pregnancy.

Factors associated with knowledge of personal gestational weight gain recommendations

Objectives

Excess adiposity (obesity and excess gestational weight gain, GWG) during pregnancy (EADP) increases risk for gestational diabetes, preeclampsia, and child and maternal obesity. Personal GWG goals predict total GWG. Some estimates suggest only 30% of pregnant women have personal GWG goals that are congruent with Institute of Medicine GWG recommendations. The primary purpose of this study was to determine the extent to which perceived pre-pregnancy weight status, healthcare provider advice, knowledge of EADP risks, and value for healthy GWG predicted knowledge of GWG recommendations. The secondary purpose was to determine sources of GWG information among pregnant women.

Methods

Pregnant women with a confirmed singleton pregnancy completed a one-time survey in obstetric clinic waiting rooms. Logistic regression analysis was used.

Results

246 predominantly African American, low income, overweight/obese women completed surveys. Average age was 25 (SD 5.3) and gestation age ranged from 7 to 40 weeks. Knowledge of pre-pregnancy weight status was the only unique predictor of GWG recommendation knowledge (B = .642, p = .03). The top three sources of GWG information were physicians, internet, and books. The least frequently reported sources of GWG information were other healthcare providers, community programs, and television.

Conclusion

In low income diverse overweight/obese pregnant women, accurate pre-pregnancy weight status perception was the only significant unique predictor of knowledge of GWG recommendations. Physicians were the preferred source of GWG information. Clinicians should have frequent, ongoing conversations about weight status with women before, during, and after pregnancy.

Obstetric and metabolic implications of excessive gestational weight gain in pregnancy

OBJECTIVE

To compare maternal characteristics, obstetric outcomes and insulin resistance in a cohort of women subdivided into those who did and those who did not exceed the Institute of Medicine (IOM) gestational weight gain guidelines.

METHODS

This is a prospective study of 621 women without diabetes. Concentrations of glucose, insulin and leptin were measured in early pregnancy and at 28 weeks. Ultrasound at 34 weeks assessed fetal anthropometry including abdominal wall width (AAW). At delivery birthweight was recorded and fetal glucose, C-peptide and leptin measured in cord blood. Insulin resistance was calculated using the HOMA equation. Outcomes in those who did and did not exceed IOM guidelines were compared.

RESULTS

Overall, 267 women (43%) exceeded IOM guidelines and 354 (57%) did not. On 34-week ultrasound women with excessive weight gain had higher fetal weights (2681 ± 356 g vs. 2574 ± 331, P = 0.001) and fetal adiposity (AAW) (5.29 ± 1.3 vs. 4.8 ± 1.2, P = 0.001). Infant birthweight and birthweight centiles were also higher in those who exceeded the guidelines. There was no difference between the two groups in maternal insulin resistance in early pregnancy, but by 28 weeks those with excessive weight gain had higher maternal HOMA indices and higher maternal leptin concentrations.

CONCLUSION

Excessive maternal gestational weight gain has significant implications for infant growth and adiposity, with potential implications for later adult health.

Perspectives about and approaches to weight gain in pregnancy: a qualitative study of physicians and nurse midwives

Background

Over one third of reproductive age women in the US are obese. Pregnancy is a strong risk factor for obesity, with excess weight gain as the greatest predictor of long term obesity. The majority of pregnant women gain more weight than recommended by the Institute of Medicine guidelines. The objective of this study was to understand prenatal care providers’ perspectives on weight gain during pregnancy.

Methods

Semi-structured qualitative interviews of 10 prenatal care providers (three family physicians, three obstetricians, and four nurse midwives) at a University Hospital in the Midwest, that included the ranking of important prenatal issues, and open-ended questions addressing: 1) general perceptions; 2) approach with patients; and 3) clinical care challenges.

Results

Providers felt that appropriate weight gain during pregnancy was not a high priority. Many providers waited until patients had gained excess weight before addressing the issue, were not familiar with established guidelines, and lacked resources for patients. Providers also believed that their counseling had low impact on patients, avoided counseling due to sensitivity of the topic, and believed that patients were more influenced by other factors, such as their family, habits, and culture.

Conclusions

Both providers and patients may benefit from increased awareness of the morbidity of excess weight gain during pregnancy. Practice-level policies that support the monitoring and management of weight gain during pregnancy could also improve care. Research that further investigates the barriers to appropriate weight gain is warranted.

Limiting excess weight gain in healthy pregnant women: importance of energy intakes, physical activity, and adherence to gestational weight gain guidelines

Few studies have investigated if compliance with energy intakes, physical activity, and weight gain guidelines attenuate postpartum weight retention (PPWR) in mothers attending prenatal classes. We investigated whether (a) daily energy intakes within 300 kcal of estimated energy requirements (EERs), (b) walking more than 5000 steps/day, (c) targeting the recommended weight gain goals for prepregnancy BMI, and/or (d) achieving weekly or total gestational weight gain (GWG) recommendations minimized PPWR in 54 women attending prenatal classes in Montreal/Ottawa, Canada. Participants completed a validated pregnancy physical activity questionnaire (PPAQ), 3 telephone-validated 24-hr dietary recalls, and wore a pedometer for one week. PPWR was measured 6 weeks after delivery. Results showed that 72% had healthy prepregnancy BMIs. However, 52% consumed >300 kcal/day in excess of their EER, 54% exceeded recommended GWG, and more overweight (93%) than normal weight women (38%) cited nonrecommended GWG targets. Following delivery, 33% were classified as overweight, and 17% were obese. Multiple logistic regressions revealed that women targeting “recommended weight gain advice” were 3 times more likely to meet total GWG recommendations (OR: 3.2, P < 0.05); women who complied with weekly GWG goals minimized PPWR (OR: 4.2, P < 0.02). In conclusion, appropriate GWG targets, lower energy intakes, and physical activity should be emphasized in prenatal education programs.
