Women's sexual health six months after a severe maternal morbidity event.

OBJECTIVE: to investigate female sexual function in women six months postpartum and to compare sexual function among women who had and who did not have severe maternal morbidity (SMM). METHOD: a cross-sectional study conducted with 110 women in the postpartum period, with and without SMM. Two instruments were used, one for the characterization of sociodemographic and obstetric variables and the Female Sexual Function Index (FSFI) for sexual function. Univariate, bivariate and regression model analyses were performed. RESULTS: FSFI scores showed 44.5% of female sexual dysfunction, of which 48.7% were among women who had SMM and 42.0% among those who had not. There were significant differences between age (P=0.013) and duration of pregnancy (P<0.001) between women with or without SMM. Among the cases of SMM, hypertensive disorders were the most frequent (83%). An association was obtained between some domains of the FSFI and the following variables: orgasm and self-reported skin color, satisfaction and length of relationship, and pain and SMM. CONCLUSION: white women have greater difficulty in reaching orgasm when compared to non-white women and women with more than 120 months of relationship feel more dissatisfied with sexual health than women with less time in a relationship. Women who have had some type of SMM have more dyspareunia when compared to women who have not had SMM.

Dose-Response Relationships between Breastfeeding and Postpartum Weight Retention Differ by Pre-Pregnancy Body-Mass Index in Taiwanese Women.

Postpartum weight retention (PWR) is a risk factor for future obesity. The role of breastfeeding in reducing PWR is not fully understood. We examined the relationship between PWR and the duration of exclusive/partial breastfeeding in 52,367 postpartum women from 2012-2016 Taiwan national breastfeeding surveys. The women were interviewed at 7-14 months postpartum. Non-linear models were fit to examine the association between PWR and breastfeeding duration. PWR adjusted means and 95% confidence intervals were plotted and compared for the duration of exclusive/partial breastfeeding in the total sample and between pre-pregnancy body-mass index (BMI) groups (underweight, normal, overweight, and obese). Women who breastfed exclusively for >30 days showed significantly lower PWR than those who did not breastfeed and those who breastfed partially for the same duration, thereafter each additional duration of 30 days being associated with an average of 0.1-0.2 kg less PWR. Women who breastfed partially for 120 days showed lower PWR than those who did not or those who ceased to breastfeed, thereafter each additional duration of 30 days being associated with an average of 0.1 kg less PWR. Duration of breastfeeding needed to achieve significantly less PWR differed between pre-pregnancy BMI groups, but the effect of exclusive breastfeeding appeared earlier in the normal weight group. Women with obesity who breastfed exclusively for >30 or partially for >180 days, had lower PWR than non-obese groups. The observed dose-response relationship between breastfeeding duration and PWR supports the "every feeding matters" approach in breastfeeding promotion. The larger effect of exclusive and partial breastfeeding on PWR in women with obesity may draw special attention of breastfeeding promotion.

Access to public health services and integral care for women during the puerperal gravid period period in Ceará, Brazil.

BACKGROUND: Over time, the Brazilian health system, a growing country, has been developing to ensure good accessibility to health goods and services. This development is focusing on the principle of universality of access and completeness of health care. In this context, we aimed to evaluate the completeness of care and universality of access for women in their pregnancy and puerperal period in Ceará, Brazil. METHODS: A descriptive, cross-sectional study based on a quantitative approach, using information collected from the database of the regulation system of the state of Ceará and data from the Prenatal Monitoring System. The research population comprised of 1701 women who delivered a baby in an obstetric reference unit in the Health Macro-Region of Cariri, Ceará, Brazil from January to December 2015. RESULTS: There was a high rate of cesarean delivery (49.7%) and a high waiting time for access to high-risk delivery (32.6%) and neonatal intensive care unit (72.9%). There was also a low percentage (41.1%) of pregnant women undergoing an adequate number of prenatal consultations, dental care (20%), educational activities (15%), visits to the maternity ward (0.1%), laboratory tests of the third trimester (29.2%) and puerperal consultation (37.9%). CONCLUSIONS: It was concluded that the Maternal and Child Health Policy, especially the Rede Cegonha, which is still under development, does not ensure access and completeness of care for women during the prenatal, delivery, and puerperal periods, thus violating their reproductive rights. The results of this study allow a critical analysis by the academia and health managers in search of strategies to improve the services of Rede Cegonha in Brazil.

Benefits of Physical Activity during Pregnancy and Postpartum: An Umbrella Review.

PURPOSE: This study aimed to summarize the evidence from the 2018 Physical Activity Guidelines Advisory Committee Scientific Report, including new evidence from an updated search of the effects of physical activity on maternal health during pregnancy and postpartum. METHODS: An initial search was undertaken to identify systematic reviews and meta-analyses published between 2006 and 2016. An updated search then identified additional systematic reviews and meta-analyses published between January 2017 and February 2018. The searches were conducted in PubMed®, CINAHL, and Cochrane Library and supplemented through hand searches of reference lists of included articles and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: The original and updated searches yielded a total of 76 systematic reviews and meta-analyses. Strong evidence demonstrated that moderate-intensity physical activity reduced the risk of excessive gestational weight gain, gestational diabetes, and symptoms of postpartum depression. Limited evidence suggested an inverse relationship between physical activity and risk of preeclampsia, gestational hypertension, and antenatal anxiety and depressive symptomology. Insufficient evidence was available to determine the effect of physical activity on postpartum weight loss, postpartum anxiety, and affect during both pregnancy and postpartum. For all health outcomes, there was insufficient evidence to determine whether the relationships varied by age, race/ethnicity, socioeconomic status, or prepregnancy weight status. CONCLUSIONS: The gestational period is an opportunity to promote positive health behaviors that can have both short- and long-term benefits for the mother. Given the low prevalence of physical activity in young women in general, and the high prevalence of obesity and cardiometabolic diseases among the U.S. population, the public health importance of increasing physical activity in women of childbearing age before, during, and after pregnancy is substantial.

Breastfeeding Difficulties, Breastfeeding Duration, Maternal Body Mass Index, and Breast Anatomy: Are They Related?

Objective: We examined the influence of maternal body mass index (BMI), and of breast and nipple anatomic variations, on breastfeeding difficulties and duration. Methods: In this prospective observational study, we collected demographic and anthropometric data from 109 mothers of full-term newborns. Women were classified as underweight, normal weight, overweight, and obese using the World Health Organization definitions and were otherwise healthy. Breast anthropometrics assessments were recorded after delivery and during hospitalization. Latching difficulties were collected as reported by the mothers. Breastfeeding duration was assessed by phone interview at 3, 6, 1 year, or more postdelivery. Results: The four prepregnancy BMI groups included 12 underweight, 59 normal weight, 20 overweight, and 18 obese women. The higher the BMI group, the larger the breast was (p = 0.005). In univariate regression, nipple diameter, nipple length, and areola diameter correlated significantly with breast size. The overall rate of latching difficulties was 15.5%, without significant differences among all four BMI groups. In multivariate analysis, the higher the BMI group the lower was the likelihood of breastfeeding at 6 months of age (odds ratio [OR] = 0.88, 95% confidence interval [CI]: 0.79-0.99), and the higher the birth order the higher was the likelihood of breastfeeding at 6 months of age (OR = 3.36, 95% CI: 1.44-7.83). Early latching difficulties predicted shorter breastfeeding duration. Conclusion: We conclude that high prepregnancy BMI has a negative impact on breastfeeding initiation and duration.

Randomized Controlled Trial of Home-Based Lifestyle Therapy on Postpartum Weight in Underserved Women with Overweight or Obesity.

OBJECTIVE: This study aimed to assess the efficacy of a home-based lifestyle intervention delivered through Parents as Teachers (PAT), a national home-visiting organization, designed to minimize excessive weight gain through 12 months post partum in socioeconomically disadvantaged (SED) African American women with overweight or obesity. METHODS: This randomized controlled trial was conducted at a single center as part of the Lifestyle Interventions for Expectant Moms (LIFE-Moms) consortium. Analysis was conducted with 185 SED African American women (BMI 25.0-45.0 kg/m2 at pregnancy onset) retained from an original sample of 267 randomized to standard PAT or PAT+Lifestyle, which embedded lifestyle therapy within standard PAT delivered prenatally and for 12 months post partum. RESULTS: Compared with standard PAT, the PAT+Lifestyle group gained less weight (2.5 kg vs. 5.7 kg; P = 0.01) and were more likely to return to their baseline weight (38.0% vs. 21.5%; P = 0.01) from baseline to 12 months post partum. There were no differences between groups in cardiometabolic outcomes, indices of glycemic control and insulin sensitivity, and plasma lipid profile. The estimated cost of PAT+Lifestyle was $81 more to deliver per family than standard PAT. CONCLUSIONS: PAT+Lifestyle decreases weight gain during pregnancy through 12 months post partum in SED African American women with overweight or obesity at the start of pregnancy with minimal additional cost.

[Assessment of rumen fill in dairy cows for evaluation of the individual feed intake in herd management]. / Bewertung der Pansenfüllung von Milchkühen zur Beurteilung der individuellen Futteraufnahme in der Bestandsbetreuung.

OBJECTIVE: Postpartal disease complexes of dairy cows are frequently related to an insufficient feed intake around calving. The study examined the relationship between the rumen fill (RF) score and the feed intake. A further aim was to evaluate whether the RF score can be used in practice to estimate the cow's individual feed intake (in kg dry mass intake or fresh-mass intake per cow). MATERIAL AND METHODS: In pluriparous cows (n = 109), the RF was scored daily according to the schema of Zaaijer and Noordhuizen (2003) modified by half-points between day 24 (±â€…4 days) ante partum (a. p.) and day 9 post partum (p. p.) as well as on days 28 (±â€…2 days) and 60 (±â€…2 days) p. p. The individual feed intake per cow was recorded. Additionally, measurements of the feed intake were performed every 4 hours over 24 hours (24-hour daily profiles) in 21 cows a. p. and in 10 cows p. p. RESULTS: There was a significant relationship between the RF score and the feed intake both a. p. and p. p. The number of days in milk greatly influenced this relationship. Immediately p. p., there was a response in the RF score of half a score with an additional intake of 3.5 kg dry matter, while a. p., a change of the PF score only occurred when the feed uptake was reduced by 18 kg dry matter. CONCLUSION: During the first week p. p., the RF score proved to be a sensitive measuring instrument for the individual feed intake. Because of its low response a. p., it was only suitable for the detection of animals at risk with a considerably reduced feed intake over several days. CLINICAL RELEVANCE: The RF score provides the most informative value during the first week p. p. to assess the increase in feed intake in the individual cow after calving. It is recommended to score the RF daily during the first 7-9 days p. p. and to evaluate it individually to detect risk animals with a reduced feed intake. During the dry period, only cows with a significantly reduced feed intake over several days can be detected and consequently treated early to prevent disorders p. p. During lactation (evaluated on days 28 and 60 p. p.), the RF score appears to be of very limited informative value regarding the individual feed intake.

Assessment of maternal cerebral blood flow velocity by transcranial Doppler ultrasound before delivery and in the early postpartum period.

OBJECTIVE: This prospective observational study aimed to identify the effects of labor on cerebral hemodynamics by measuring the middle cerebral artery (MCA) blood flow velocity by transcranial Doppler ultrasound (TCD), and the related factors just before delivery and within the 24 h after delivery. METHODS: The study included 35 healthy pregnant women with a gestational age of >37 weeks who were in labor and a control group including healthy, age-matched, nonpregnant women (n = 24). Demographic characteristics and significant clinical information of pregnant women were recorded. The MCA blood flow velocity was assessed by TCD just before and within 24 h after delivery. The parameters assessed by TCD were mean cerebral blood flow velocity (MCBFV), peak systolic velocity (PSV), pulsatility index (PI), resistance index (RI), and systolic/diastolic ratio. RESULTS: There was no significant difference between the pregnant and nonpregnant women regarding age (27 ± 5 years versus 28 ± 7 years; p = .751). The MCBFV, PSV, PI, and RI showed a significant increase within the 24 h after delivery as compared with those before delivery. Comparison of the pregnant women with the control group in terms of the values of all parameters related to the MCA blood flow velocity revealed that the values that were significantly low before delivery reached to the level of the control group after delivery Conclusion: The findings of this study demonstrated that the blood flow velocity of the MCA decreased during the late pregnancy period and increased in the early postpartum period to the level similar to that of the nonpregnant group.

Determinants of the utilization of postpartum family visits: Evidence from rural areas of Eastern China.

BACKGROUND: Postpartum Family Visits (PFVs) have been advocated as a way to improve health outcomes for puerperal women and their newborns. This study aimed to identify individual factors associated with the utilization of PFVs in rural Jiangsu Province, China. METHODS: We employed responses of the household survey in Jiangsu province, part of the National Health Service Survey (NHSS), a nationally representative survey in China. The data analysis framework was designed based on Andersen's behavioral model. The outcome variables included nonuse and deficient use of PFVs, and the explanatory variables were organized into three hierarchical levels: predisposing, enabling and need factors. Univariate analysis and multivariate logistic regression analysis were conducted to examine the impact of the three hierarchical levels on PFVs utilization. RESULTS: A total of 884 rural women who had a childbearing history in the prior five years answered PFVs questions. About 23.4% of them had never received any PFVs, and 40.4% received <3 visits. In the results of multivariate logistic regression, educational level (OR = 0.43, 95% CI: 0.24-0.77), income (OR = 0.62, 95% CI: 0.43-0.88), the distance from the nearest hospital (OR = 1.49, 95% CI: 1.07-2.07) and parity (OR = 2.17, 95% CI: 1.54-3.05) had significant relationship with nonuse. Factors significantly associated with deficient use of PFVs included employment (OR = 0.62, 95% CI: 0.39-0.98), the distance from the nearest hospital (OR = 1.73, 95% CI: 1.26-2.36), level of delivery institution (OR = 1.57, 95% CI: 1.14-2.17), and parity (OR = 1.45, 95% CI: 1.03-2.05). CONCLUSION: The study found lower Social Economic Status (SES), long distance with primary health institutions, and the increased need for services stemming from multi-parity reduced the likelihood of nonuse or deficient use of PFVs in rural areas. Multiparous, low SES women and those living far away from primary health institutions should be paid more attention to assure the coverage of postpartum care.

Postpartum Changes in Mood and Smoking-Related Symptomatology: An Ecological Momentary Assessment Investigation.

Introduction: Postpartum smoking relapse is a highly prevalent public health problem. Mood and breast feeding are significantly associated with smoking relapse, although less is known about the temporality of these relationships. Therefore, this study utilized ecological momentary assessments (EMA) to prospectively examine changes in mood and smoking-related symptomatology in relationship to three events-childbirth, termination of breast feeding, and smoking relapse. We expected all three events to significantly alter mood and smoking-related symptomatology. Methods: We enrolled a sample of pregnant women who had recently quit smoking and intended to remain quit during the postpartum. Participants were randomized to active/placebo progesterone to prevent postpartum relapse. Participants also completed daily EMA to collect data mood and smoking-related symptomatology as well as our three events of interest. Results: Participants (n = 46) were, on average, 26.5 ± 0.8 years old and, prior to pregnancy, smoked 10.1 ± 0.7 cigarettes/day. We noted a number of significant within- and between-subject relationships. For example, participants reported a 24% decline in negative affect after childbirth (p = .0016). Among those who relapsed to smoking (n = 23), participants randomized to placebo had a significant increase in cigarette craving after relapse (ß = 1.06, 95% confidence interval [CI] = 0.62 to 1.49, p value = .0003), whereas participants randomized to active progesterone did not (ß = 0.63, 95% CI = -0.35 to 1.62, p value = .1824). Conclusions: These observations suggest that mood and smoking-related symptomatology are influenced by childbirth, breast feeding, smoking relapse, and use of exogenous progesterone. Future research should explore how these observations may inform novel postpartum smoking relapse-prevention interventions. Implications: Postpartum smoking relapse has been a persistent public health problem for more than 40 years. Although a number of significant predictors of postpartum smoking relapse have been identified (eg, depression and breast feeding), much of these analyses have relied on cross-sectional and/or self-reported retrospective data. Therefore, for the first time, we utilized ecological momentary assessment to explore the effect of childbirth, termination of breast feeding, and smoking relapse on mood and smoking-related symptomatology (eg, craving). Numerous significant relationships were observed, including a 96% increase in craving after smoking relapse. These novel observations can inform new and effective postpartum smoking relapse-prevention programs.

A Postpartum Sleep and Fatigue Intervention Feasibility Pilot Study.

The purpose of this pilot study was to evaluate the feasibility, acceptability, and cost of a self-management intervention for postpartum fatigue and sleep in socioeconomically disadvantaged urban women. Helping U Get Sleep (HUGS) is a theory-guided intervention developed from the Individual and Family Self-Management Theory. Medicaid-enrolled participants in the United States were recruited from an inpatient postpartum unit. Treatment and attention control interventions were delivered (15 HUGS, 12 comparison) at a week 3 postpartum home visit and 4 follow-up phone calls. Over the 9-week protocol, the HUGS group demonstrated significant improvements in subjective fatigue and subjective sleep disturbance relative to the comparison group. The HUGS intervention was feasible and acceptable, delivered on average, in 100 min and costing US$79 per participant.

Energy expenditure in the immediate postpartum period: Indirect calorimetry versus predictive equations.

OBJECTIVE: The aim of this study was to evaluate the resting energy expenditure (REE) of postpartum women by indirect calorimetry and to provide the most appropriate predictive equations to estimate it. METHODS: This was a cross-sectional study with 79 women in the maternity unit of a Brazilian city hospital. Information regarding age, income, gestational age, and breastfeeding was collected. Height, weight, and body composition were measured. We measured REE by indirect calorimetry and predicted REE using eight equations. Analysis of comparison, correlation, agreement, and accuracy was performed. RESULTS: The median of measured REE was 1224 kcal (95% confidence interval [CI], 1157.4-1330), and the predicted REE ranged from 1213.8 (95% CI, 1207.3-1261.9) to 1553.1 kcal (95% CI, 1430.8-1488.5). No difference was found in REE between mothers who breastfed and those who did not (P = 0.994); however, there was a positive correlation with lean mass (r = 0.336; P = 0.003) and weight (r = 0.237; P = 0.036). The best predictor of REE was the Harris Benedict equation, with lower difference (P = 0.876), better median of adequacy (99.8%), and better interclass correlation coefficient (0.289). The Schofield equation was next, with greater percentage of accuracy (33.3%) and lower opposite agreement (7.6%). CONCLUSIONS: All predictive equations showed low agreement and accuracy, and, in most cases, the results were overestimated. These findings indicate the need for continued studies to propose more suitable methods to determine the energy requirements for this population.

The fourth trimester: a critical transition period with unmet maternal health needs.

After childbirth, most American women are not scheduled for follow-up care for 6 weeks, and this visit is poorly attended. Many new mothers feel unprepared for the common health issues they encounter and are uncertain of whom to contact. To improve care, the 4th Trimester Project is bringing together mothers, health care providers, and other stakeholders to explore what families need most from birth to 12 weeks postpartum. Eighty-seven individuals convened in March 2016 in Chapel Hill, NC. Four major topic areas emerged: (1) the intense focus on women's health prenatally is unbalanced by infrequent and late postpartum care; (2) medical practice guidelines often do not align with women's experiences and constraints; (3) validation of women as experts of their infants and elevating their strengths as mothers is necessary to achieve health goals; and (4) mothers need comprehensive care, which is difficult to provide because of numerous system constraints. Considerations for improving postpartum services include enabling more convenient care for families that is holistic, culturally appropriate, conversation based, and equitable. Maternal health issues in the fourth trimester intersect and can compound one another. Enhanced collaboration among health care providers may improve the focus of clinical interactions to address the interrelated health issues most important to women.

Chronic Stress and C-Reactive Protein in Mothers During the First Postpartum Year.

OBJECTIVE: Elevated levels of C-reactive protein (CRP) are associated with increased risk of cardiovascular and metabolic disease. The current study tested associations between psychosocial stress and CRP in a large sample of women during the first postpartum year. METHODS: We analyzed data collected by the five-site Community Child Health Network study, which studied a predominately poor population. Participants (n = 1206 women; 54% African American, 23% white, 23% Hispanic/Latina) were recruited shortly after the birth of a child. Multiple linear regression analyses tested associations of psychosocial stress in several life domains (financial, neighborhood, family, coparenting, partner relationship, discrimination, and interpersonal violence) with log-transformed CRP concentrations at 6-month and 1-year postpartum. RESULTS: Forty-eight percent of participants showed evidence of elevated CRP (≥3 mg/L) at 6-month postpartum, and 46% had elevated CRP at 12-month postpartum. Chronic financial stress at 1-month postpartum predicted higher levels of CRP at 6- (b = .15, SE = .05, p = .006) and 12-month postpartum (b = .15, SE = .06, p = .007) adjusting for race/ethnicity, income, education, parity, health behaviors, and chronic health conditions, though associations became nonsignificant when adjusted for body mass index. CONCLUSIONS: In this low-income and ethnic/racially diverse sample of women, higher financial stress at 1-month postbirth predicted higher CRP. Study findings suggest that perceived financial stress stemming from socioeconomic disadvantage may be a particular deleterious form of stress affecting maternal biology during the year after the birth of a child.

Assessment, Management, and Health Implications of Early-Onset Preeclampsia.

Early-onset preeclampsia is a serious condition of pregnancy with the potential for adverse maternal and fetal health outcomes. A strong body of evidence supports the need for postpartum follow-up and health counseling, because these women and their offspring are at risk for future cardiovascular disease; nurses play a key role in this education. An understanding of the diagnosis, risk screening for, pathogenesis, and management of severe preeclampsia and its sequelae, such as intrauterine growth restriction and pulmonary edema, enables nurses to develop a comprehensive plan of care that will support women and their families through this challenging and dynamic complication of pregnancy.

Ultrasound Assessment of Lower Uterine Segment Thickness During Pregnancy, Labour, and the Postpartum Period.

OBJECTIVES: To evaluate the normal ranges of lower uterine segment (LUS) thickness throughout pregnancy in women without a previous cesarean and to evaluate the relationship between ultrasound and intraoperative LUS thickness. METHODS: We assessed LUS thickness using transabdominal and transperineal longitudinal scan at each week of gestation, during labour, and in the postpartum period in 1000 pregnant women without previous CS. Secondly, we assessed LUS thickness immediately before CS (using ultrasound) and intraoperatively (using ophthalmic calipers) immediately before delivery of the fetus in 35 women with a previous CS and 29 women without previous CS undergoing elective CS before labour. RESULTS: We performed 20 307 LUS thickness measurements in between 119 and 944 women at each week of gestation, in 944 women during labour, and in 936 women after delivery. We observed a strong relationship between transabdominal and transperineal ultrasound (P < 0.001) and an inverse correlation between LUS thickness and gestational age (P < 0.001), with a mean thickness of 5.1 ± 1.4 mm at 20 weeks, 3.6 ± 1.3 mm at 30 weeks, and 2.3 ± 0.6 mm at 40 weeks of gestation. In women undergoing elective CS, we observed a strong relationship between antepartum and intraoperative LUS thickness (P < 0.001), with mean thicknesses of 2.2 ± 0.7 mm in 28 women without thinning of LUS; 0.8 ± 0.1 mm in four women with grade II uterine scar dehiscence; and 0.4 ± 0.1 mm in three women with grade III dehiscence. A LUS myometrial thickness less than 1.2 mm could have predicted all grade II and grade III uterine scar dehiscences without false-positive cases. CONCLUSION: LUS thickness decreases with gestational age and correlates strongly with the intraoperative LUS thickness in women with a previous CS.

Assessment of nasal airway patency during pregnancy and postpartum period: correlation between subjective and objective techniques.

OBJECTIVES: This study aims to determine the physiological changes in a pregnant woman's nasal airway, the frequency of pregnancy rhinitis, and the correlation among anterior rhinoscopy (AnR), anterior rhinomanometry (ARM), and subjective nasal obstruction score as she progresses through pregnancy into the postpartum period (PPP). PATIENTS AND METHODS: Twenty non-smoking healthy pregnant women aged 19-35 (average 27.5±4.7) without a history of either respiratory allergy or chronic nasal or sinus problems were included in the study. Detailed history taking, AnR, and ARM were performed by the same ear nose and throat specialist at each trimester and postpartum second week. From then on, the participants scored, subjectively, morning levels of nasal obstruction (0= none, 1= slight, 2= moderate, 3= severe, 4= total obstruction). RESULTS: The AnR scores were low and the ARM findings were in normal range in the first trimester. Increasing AnR scores through pregnancy and decreasing AnR scores at PPP were statistically significant. Similarly, the ARM findings increased through pregnancy and decreased to normal levels at PPP; however, these changes among trimesters and PPP were not statistically significant. CONCLUSION: Anterior rhinomanometry and AnR are useful tools in the determination of nasal physiological changes as pregnancy progresses to PPP.

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.

Gestational dietary patterns are not associated with blood pressure changes during pregnancy and early postpartum in a Brazilian prospective cohort.

PURPOSE: To identify gestational dietary patterns and evaluate the association between these patterns and the blood pressure (BP) rate of change during pregnancy and the postpartum. METHODS: Prospective cohort study composed of 191 healthy pregnant women. Systolic BP (SBP) and diastolic BP (DBP) were obtained at the 5th-13th, 20th-26th, 30th-36th gestational weeks, and with 30-45 days postpartum. A food frequency questionnaire administered at the 30th-36th gestational week was used to measure dietary intake during pregnancy. Principal component analysis was performed to identify the dietary patterns. A longitudinal linear mixed-effects regression model was used to evaluate the association between the dietary patterns and BP (adjusted for time elapsed after conception and the women's age, education, parity, body mass index and total energy intake). RESULTS: Three gestational dietary patterns were identified: healthy, common-Brazilian and processed. SBP/DBP mean values (SD) were 110.1 (9.0)/66.9 (7.5), 108.7 (9.0)/64.9 (6.7), 111.3 (9.2)/67.0 (6.9) and 115.0 (10.7)/73.7 (8.6) mmHg at the first, second and third gestational trimesters and postpartum, respectively. Women with higher/lower adherence to the processed pattern presented SBP of 117.9 and 113.0 mmHg (P = 0.037), respectively, during postpartum. No association was found between any of the three dietary patterns and SBP in the multiple longitudinal linear regression models, whereas 1 SD increase in the common-Brazilian pattern was associated with a small change of DBP (ß = 0.0006; 95% CI 4.66e-06, 0.001; P = 0.048). CONCLUSION: The three dietary patterns identified revealed no association with changes of SBP and DBP levels during pregnancy and at early postpartum in this sample of healthy Brazilian women.
