Weight Loss, Gain, or Stability from 6 Weeks to 6 Months Postpartum: Associations with Depressive Symptoms and Behavioral Habits.

Background: Studies examining postpartum retained weight referenced to prepregnant body weight may mask weight gained after 6 weeks postpartum, a potential unrecognized factor contributing to weight increases after pregnancy. Materials and Methods: Using data from a longitudinal study, we examined three weight patterns from 6 weeks to 6 months postpartum (>2.3 kg gain; >2.3 kg loss; and ±2.3 kg as stable weight) in 302 low-income women. Predictor variables included perinatal variables, health habits, and depression risk at 3 and 6 months postpartum. Results: Mean weight changes were weight-gain group: 5.77 kg, standard deviation (SD) = 2.57; weight loss group: -4.79 kg, SD = 2.10; and stable group: 0.05 kg, SD = 1.24. The odds of gaining weight compared with stable weight increased with prepregnant overweight/obesity (adjusted odds ratio [aOR] = 3.22, 95% confidence interval [CI] = 1.74-6.00), and decreased with a first birth (aOR = 0.47, 95% CI = 0.24-0.93). The odds of losing weight increased with excessive gestational weight gain (aOR = 2.40, 95% CI = 1.10-5.21) and depression risk at 6 months (aOR = 2.57, 95% CI = 1.40-4.72), and decreased with prepregnant overweight/obesity (aOR = 0.49, 95% CI = 0.25-0.94). Health habits were not associated with weight gain or loss. Conclusions: Women with high body mass index (BMIs) may need added postpartum care to avoid gaining weight. Weight loss, although welcomed, may be secondary to depression risk. In both cases, low-cost, effective, and targeted care during the extended postpartum period could benefit women's health.

Weight-Loss Resilience Among Low-Income Postpartum Women: Association With Health Habits.

Using a weight resilience framework, health habits of diet and physical activity, social support, and perceived stress were compared in women who lost weight (resilient) and those who did not lose or gained weight (nonresilient) during a weight-loss intervention. Participants were low-income postpartum women participating in a 13-week randomized treatment-control group intervention, with 20 of 50 classified as resilient in losing weight. Measures included the Postpartum Support Scale, the Perceived Stress Scale, and health habit items from the Self Care Inventory. Weight-loss resilient women showed significantly more frequent healthful dietary habits, such as eating a nutritious breakfast, and less frequent unhealthy habits, such as substituting junk food for meals, and less perceived stress than their nonresilient counterparts at both the midpoint and end of the study. Weight-loss resilient women also showed significantly more frequent physical activity habits at the end of the study. No social support differences were found.

Development and evaluation of a mother-centered toolkit for postpartum behavioral and psychosocial health.

The well-being of mothers and infants is influenced by mothers' behavioral and psychosocial health (B&PH), yet it is often neglected during healthcare visits. To address this gap, this study aimed to develop and evaluate acceptability of a postpartum toolkit (screening questionnaire, feedback template, and decision aid) to promote B&PH. Using a decision-making model and participatory design (N = 24), a B&PH screening questionnaire was refined, and prototypes of feedback templates and decision aids for selecting health goals were developed. Most mothers in this multi-ethnic sample rated the resulting toolkit as easy to understand/use and useful, and reported they were likely to act on their health goals. Toolkit ease of use and usefulness ratings were largely unrelated to education, ethnicity, and acculturation. In conclusion, findings support the toolkit's acceptability and applicability to women of diverse backgrounds. The toolkit is a promising strategy to engage mothers in setting goals to promote B&PH.

e-Health and new moms: Contextual factors associated with sources of health information.

OBJECTIVE: Guided by the Uses and Gratifications approach, to examine mothers' use and preference of e-Health media, and associated contextual factors. DESIGN AND SAMPLE: Cross-sectional survey of 165 mothers (White, African-American, and Hispanic) from a stratified random sample. MEASURES: Use of online media about mother-baby care; favorite websites about motherhood and best-liked features of Web sites; channel preferences (Web site, postal mail, text) for receiving three types of health information; and contextual factors, e.g., education. RESULTS: Media use ranged from 96% for health information searches about babies to 46% for YouTube viewing about mother-baby topics. Contextual factors, such as education, were associated with media use. Babycenter was the most frequently reported favorite Web site and rich, relevant information was the best-liked feature. Across three health topics (weight, stress/depression, parenting) mothers preferred receiving information by Web site, followed by postal mail and least by text messaging (χ2 statistics, p < .001). Stress and race/ethnicity were among factors associated with preferences. CONCLUSIONS: Mothers widely used e-Health related media, but use was associated with contextual factors. In public health efforts to reach new mothers, partnering with mother-favored Web sites, focusing on audience-relevant media, and adopting attributes of successful sites are recommended strategies.

Behavioral and Psychosocial Health of New Mothers and Associations With Contextual Factors and Perceived Health.

OBJECTIVE: To test the association of behavioral and psychosocial health domains with contextual variables and perceived health in ethnically and economically diverse postpartum women. DESIGN: Mail survey of a stratified random sample. SETTING: Southwestern community in Texas. PARTICIPANTS: Non-Hispanic White, African American, and Hispanic women (N = 168). METHODS: A questionnaire was sent to a sample of 600 women. The adjusted response rate was 32.8%. The questionnaire covered behavioral (diet, physical activity, smoking, and alcohol use) and psychosocial (depression symptoms and body image) health, contextual variables (race/ethnicity, income, perceived stress, and social support), and perceived health. Hypotheses were tested using linear and logistic regression. RESULTS: Body image, dietary behaviors, physical activity behaviors, and depression symptoms were all significantly correlated (Spearman ρ = -.15 to .47). Higher income was associated with increased odds of higher alcohol use (more than 1 drink on 1 to 4 days in a 14-day period). African American ethnicity was correlated with less healthy dietary behaviors and Hispanic ethnicity with less physical activity. In multivariable regressions, perceived stress was associated with less healthy dietary behaviors, increased odds of depression, and decreased odds of higher alcohol use, whereas social support was associated with less body image dissatisfaction, more physical activity, and decreased odds of depression. All behavioral and psychosocial domains were significantly correlated with perceived health, with higher alcohol use related to more favorable perceived health. In regressions analyses, perceived stress was a significant contextual predictor of perceived health. CONCLUSION: Stress and social support had more consistent relationships to behavioral and psychosocial variables than race/ethnicity and income level.

Mental health literacy and postpartum depression: a qualitative description of views of lower income women.

The purpose of this study is to understand mental health literacy (MHL) (Jorm, 2000) in lower income women postpartum and share participant experiences of recognizing and seeking help for depressive symptoms. Focus group textual data were received from 25 participants who completed a weight and psychosocial health longitudinal study. Iterative content data analysis using Jorm's framework provided thematic understandings descriptive of MHL. Women recognized behavioral changes indicating mental distress, but fears prevented them from seeking help, and some resorted to risky behaviors. This framework could guide providers to identify women who may benefit from early intervention for postpartum depressive symptoms.

Cumulative poor psychosocial and behavioral health among low-income women at 6 weeks postpartum.

BACKGROUND: During the postpartum period, women may experience unfavorable psychosocial and behavioral health in multiple domains with adverse effects on parenting and maternal and infant health. Yet, little is known about the accumulation of poor health across the domains of depressive symptoms; body image; diet and physical activity; substance use including smoking and alcohol; and general self-care at 6 weeks postpartum, the usual end of maternity care. OBJECTIVES: The aims of this study were to evaluate relationships among the domains comprising psychosocial and behavioral health and to examine the distribution and risk factors associated with cumulative poor psychosocial and behavioral health at 6 weeks postpartum. METHODS: This study was a secondary analysis of cumulative poor health assessed by self-report scales for depressive symptoms, body image dissatisfaction, diet and exercise, substance use, and general self-care among 419 low-income White, African American, and Hispanic women at 6 weeks postpartum. Multivariable Poisson and logistic regression were used in key analyses. RESULTS: The correlation among psychosocial and behavioral domains had a range of r = .50-.00. In this sample of women, 45% had two or more domains in which they had poor health. The model testing risk factors for cumulative poor health was significant (likelihood ratio chi-square = 39.26, df = 11, p < 0.05), with two significant factors: not exclusively breastfeeding (odds ratio [OR] = 1.459, 95% confidence interval [CI] [1.119, 1.901]) and Hispanic ethnicity (OR = 0.707, 95% CI [0.582, 0.858], psuedo-R = .029). Within individual domains, significant risk factors (body mass index, not exclusively breastfeeding, ethnicity, education level, and parity) varied by domain. DISCUSSION: Many low-income women postpartum have poor psychosocial and behavioral health in multiple domains, which constitute areas for health promotion and early disease prevention.

Ethnic-specific weight-loss interventions for low-income postpartum women: findings and lessons.

Promoting weight loss among overweight low-income postpartum women has proven difficult. The study's aims were to pilot-test ethnic-specific weight-loss interventions using randomized control-group designs for White/Anglo (n = 23), African American (n = 25), and Hispanic low-income postpartum women (n = 23) and draw lessons from psychosocial data and follow-up interviews. Interventions lasting 13 weeks were offered in group settings in the community. Similar to other randomized trials with low-income mothers, weight changes between intervention and control groups were nonsignificant in each ethnic group; however, changes correlated significantly with self-efficacy (Spearman r = .50) for White/Anglo women and self-efficacy (Spearman r = -.48) and perceived stress (Spearman r = .48) for African American women. In follow-up interviews, women felt interventions gave a good foundation for weight loss, but program and situational factors affected participation and weight loss. Control groups (mailed interventions later) were generally more pleased with their assignment than intervention groups.

Self-efficacy scale for weight loss among multi-ethnic women of lower income: a psychometric evaluation.

OBJECTIVE: This study examined test-retest reliability, internal consistency, and construct and predictive validity of the Physical Activity and Nutrition Self-Efficacy (PANSE) scale, an 11-item instrument to assess weight-loss self-efficacy among postpartum women of lower income. METHODS: Seventy-one women completed the PANSE scale and psychosocial measures at baseline and at 7 and 13 weeks of a pilot study of weight loss. RESULTS: Test-retest reliability of PANSE scores was r = 0.55 (P < .01). Cronbach α was r = 0.89. Construct validity was supported by correlations with less-healthful behaviors (r = -0.33, P = .005), perceived stress (r = -0.24, P = .04), and decisional balance (r = 0.25, P = .03). PANSE change scores correlated with intervention group weight changes (r = -0.54, P < .01), although baseline scores did not. One factor emerged (loadings .80 to .57). CONCLUSIONS AND IMPLICATIONS: The PANSE scale demonstrated adequate reliability, internal consistency, construct validity, and moderate predictive validity. Replication is needed to confirm study findings.

The distribution of weight-related risks among low-income women during the first postpartum year.

OBJECTIVE: To describe the distribution of weight-related risks (weight retention and overweight/obese status) during the first postpartum year and determine if risk distributions differ by race/ethnicity, time, age, or parity. DESIGN: Secondary analysis of a longitudinal data set from 1- to 3-days to 12-months postpartum. SETTING: Initial recruitment was from a community hospital. PARTICIPANTS: Two hundred and forty-seven (White, African American, or Hispanic) low-income women. RESULTS: At 1- to 3-days postpartum weight-related risks were distributed as follows: 6.1% no risk, 17.0% significant postpartum weight retention, 12.1% overweight/obese, and 64.8% both weight-related risks; at 12 months, the distribution was 32.4%, 8.9%, 16.6%, and 42.1%, respectively. Distributions differed by race/ethnicity at 6-months (χ² =16.1, p=.013) and 12-months postpartum (χ² =19.7, p=.003). Having both weight-related risks (vs. not) at 12 months was 3.1 (odds ratio [OR]) times more likely (95% confidence interval [CI], 1.6, 6.2) for African American and 2.4 (OR) times more likely (95% CI[1.3, 4.6]) for Hispanic than White women. Having two risks decreased significantly only between 1 to 3 days and 6 weeks (p = .000). Maternal parity, but not age, was associated with weight-related risk distributions on four of five time points. CONCLUSION: Despite changes in the weight-related risk distributions from 1- to 3-days to 6-weeks postpartum, the proportion of African American and Hispanic women with weight-related risk (especially having two weight-related risks) remains high at 12-months postpartum.

Ethnic-specific perceptions of altered control among American women: implications for health promotion programs after pregnancy.

This study describes some ethnically diverse psychosocial and behavioral contexts that influence low-income postpartum women's ability to focus on their health. Content analysis was conducted on data from ethnically concordant focus groups of low-income American Anglo, African American, and Hispanic women 12 to 24 months postpartum. All women described altered sense of "perceived control" as the context contributing to their postpartum health status, but sources and management of this perception varied by ethnicity. Effective health promotion interventions may include self-image building activities, stress management strategies and interventions that include family members but should address unique ethnic-specific contexts of low-income mothers.

Developing health promotion interventions: a Multisource Method applied to weight loss among low-income postpartum women.

Developing focused and relevant health promotion interventions is critical for behavioral change in a low-resource or special population. Evidence-based interventions, however, may not match the specific population or health concern of interest. This article describes the Multisource Method (MSM), which, in combination with a workshop format, may be used by health professionals and researchers in health promotion program development. The MSM draws on positive deviance practices and processes, focus groups, community advisors, behavioral change theory, and evidence-based strategies. Use of the MSM is illustrated in the development of ethnic-specific weight loss interventions for low-income postpartum women. The MSM may be useful in designing future health programs designed for other special populations for whom existing interventions are unavailable or lack relevance.

Altered perceptions of personal control about retained weight and depressive symptoms in low-income postpartum women.

Postpartum weight retention and depressive symptoms have a high prevalence among low income women. This qualitative study describes low-income women's experiences of weight changes and depressive symptoms during the late postpartum period. Women (n = 25) who were either overweight or had depressive symptoms, or both, at 12 months postpartum participated in an ethnically-congruent focus group. Women's experiences indicated altered personal control related to retained postpartum weight and depressive feelings. Retained weight negatively affected self-esteem and family functioning. Depression left women feeling isolated yet reluctant to seek help. These findings could provide the basis for health promotion interventions relevant to this population.

Applying the concept of positive deviance to public health data: a tool for reducing health disparities.

The concept of positive deviance (PD), which highlights uncommon practices that reduce risk in low-resource communities, has been effective in community mobilization and programming to improve health outcomes. We present a protocol for extending the concept to analysis of existing public health data. The protocol includes assessing whether PD fits the situation, identifying positive deviants, and identifying behaviors associated with positive deviants' healthy outcomes. Analyzing existing datasets from a PD perspective may aid public health nurses in efforts to reduce health disparities. The effectiveness of our protocol will be clarified in future research.

Measuring dietary intake in nursing research.

Accurately assessing dietary intake is an essential component of international health research to identify nutritional deviations that may place people at risk for developing chronic diseases. Accurate assessment may be hampered by failure to address known measurement problems with traditional dietary assessment tools. This article describes the application and advantages and disadvantages of 5 frequently used dietary assessment methods, discusses the management of measurement error common to each, and recommends use of these methods in community-based health research. Using complementary assessment methods at multiple measurement points enhances the reliability of the findings. Assessing overall dietary quality is consistent with a holistic approach to interventions designed to improve health and is a valuable methodology for nutritional research. Using innovative approaches may more accurately identify dietary patterns that contribute to disease development. Although complex, examining nutritional intake in health research is essential to determining an individual's disease risk status and response to treatment.

The structure of thriving/distress among low-income women at 3 months after giving birth.

This article explores the dimensionality of thriving among low-income Anglo, African American, and Hispanic women using factor analysis of psychosocial, behavioral, and weight measures at 3 months postpartum. Three factors were extracted for each ethnic group. The first and most robust factor was psychosocial distress, which encompassed stress, depressive symptoms, (low) social support, (unhealthy) lifestyle, and (less favorable) body image. For Anglo and Hispanic women, self-regulation also loaded on the distress factor. The findings suggest that interventions to ameliorate psychosocial distress among low-income women, regardless of ethnicity, may need to consider a comprehensive range of intervention content.

Trajectory of weight changes in the first 6 weeks postpartum.

OBJECTIVE: To determine the trajectory of postpartum weight changes and to examine associations between weight change in the first 6 weeks postpartum and demographic, clinical, psychosocial, and behavioral variables. DESIGN: Prospective, longitudinal design. SETTING: Community hospital and university research setting. PARTICIPANTS: 26 low-income women (9 White, 8 Black, and 9 Hispanic) with uncomplicated term pregnancies. MAIN OUTCOME MEASURE: Body mass index measured weekly. RESULTS: Among White women, body mass index decreased significantly for the first 3 weeks of the postpartum period. Black women experienced a significant reduction in body mass index for only the first 2 postpartum weeks. Similarly, the postpartum body mass index decreased for the first 2 weeks for Hispanic women. Prepregnancy body mass index and gestational weight gain each had a significant positive effect on postpartum body mass index. Perception of social support at 4 weeks had a significant positive effect on postpartum body mass index in Black women. CONCLUSIONS: The trajectory of weight change was nonlinear with large initial weight losses during the first 2 to 3 weeks postpartum followed by weight plateaus for the remainder of the first 6 weeks postpartum.

Retention of pregnancy-related weight in the early postpartum period: implications for women's health services.

OBJECTIVE: To examine the proportion of women who reached their prepregnant weight at 6 weeks postpartum and the average amount of weight retained or lost by this time; to determine predictors of early (6 week) postpartum weight retention; and to propose related implications for women's health care and services. DATA SOURCES: The literature review was based on a search of Medline for the years 1986 to 2004 using the keywords postpartum weight with inclusion of additional articles known to the authors that did not appear in the electronic search. STUDY SELECTION: The resulting 83 articles were scrutinized to identify those that reported data on weight retention at 6 weeks postpartum (range, delivery to 3 months) and associated anthropometric, social, obstetric, or behavioral predictors. A total of 12 articles met inclusion criteria for the review. DATA EXTRACTION: Data were extracted related to the proportion of women achieving their postpartum weight at 6 weeks postpartum, the amount of weight retained or lost up to 6 weeks postpartum, and predictors of amount of weight retained or lost. DATA SYNTHESIS: On average, at 6 weeks postpartum, women retain 3 to 7 kg of the weight gained during pregnancy, with at least two thirds exceeding their prepregnant weights. Gestational weight gain is the most significant predictor of weight retention. CONCLUSIONS: Women vulnerable to obesity and weight gain need weight-related health care and improved access to such care to promote weight loss after 6 weeks postpartum.

Physical activity in low-income postpartum women.

PURPOSE: To validate the 7-day physical activity recall (PAR), including alternative PAR scoring algorithms, using pedometer readings with low-income postpartum women, and to describe physical activity patterns of a low-income population of postpartum women. METHODS: Forty-four women (13 African American, 19 Hispanic, and 12 White) from the Austin New Mothers Study (ANMS) were interviewed at 3 months postpartum. Data were scored alternatively according to the Blair (sitting treated as light activity) and Welk (sitting excluded from light activity and treated as rest) algorithms. Step counts based on 3 days of wearing pedometers served as the validation measure. FINDINGS: Using the Welk algorithm, PAR components significantly correlated with step counts were: minutes spent in light activity, total activity (sum of light to very hard activity), and energy expenditure. Minutes spent in sitting were negatively correlated with step counts. No PAR component activities derived with the Blair algorithm were significantly related to step counts. The largest amount of active time was spent in light activity: 384.4 minutes with the Welk algorithm. Mothers averaged fewer than 16 minutes per day in moderate or high intensity activity. Step counts measured by pedometers averaged 6,262 (SD = 2,712) per day. CONCLUSIONS: The findings indicate support for the validity of the PAR as a measure of physical activity with low-income postpartum mothers when scored according to the Welk algorithm. On average, low-income postpartum women in this study did not meet recommendations for amount of moderate or high intensity physical activity.

Do low-income women attain their pre-pregnant weight by the 6th week of postpartum?

OBJECTIVES: To assess the proportion of women attaining pre-pregnant weight, and to ascertain the predictors of amount of retained weight at 6 weeks postpartum, in a tri-ethnic sample of low-income women. DESIGN: Short-term longitudinal design from post-delivery to 6 weeks postpartum. PARTICIPANTS: 419 African-American, Hispanic, and White women receiving perinatal care funded by Medicaid. MAIN OUTCOME VARIABLES: Proportion of women attaining pre-pregnant weight at 6 weeks postpartum; the amount of weight retained at 6 weeks postpartum. RESULTS: Fifteen percent of women attained their pre-pregnant weight at 6 weeks postpartum. In multiple regression analysis, maternal weight gain during pregnancy was the predominant predictor (B=.88, SE=.02, P=.000). Hispanic ethnicity (B=.69, SE=.33, P=.039) and the interaction between maternal weight gain and gestational length (B=-.04, SE=.02, P=.032) made small, independent contributions to amount of retained weight at 6 weeks postpartum. The interaction of ethnicity and maternal age predicted 1.3% of the variance in retained weight, but this was not significant. Health practices were not associated significantly with the amount of weight retained at 6 weeks postpartum. CONCLUSIONS: The majority of women did not return to their pre-pregnant weight by 6 weeks postpartum. The amount of retained weight after delivery is largely influenced by prenatal maternal weight gain.
