A concurrent prenatal exercise program increases neonatal and placental weight and shortens labor: The GESTAFIT project.

OBJECTIVE: To explore the influence of a supervised concurrent exercise-training program during pregnancy on maternal and neonatal birth-related outcomes and type of birth. METHODS: One hundred and fifty-nine Caucasian pregnant women from the GESTAFIT project participated in this quasi-experimental study and were allocated into control [(n = 86), (age 33.1 ± 4.8 years old, BMI 24.8 ± 4.1 kg/m2 )] or exercise group [(n = 50) (age 33.1 ± 4.1 years old, BMI: 24.7 ± 4.1 kg/m2 )]. The exercise group followed a 60-min 3 days/week concurrent (aerobic and strength) training program from the 17th gestational week until birth. Maternal and neonatal birth-related outcomes (i.e., gestational age at birth, duration of labor, placental and neonatal weight and type of birth) were collected from obstetric medical records. Umbilical arterial and venous blood gas analysis were assessed after birth. RESULTS: The exercise group increased average duration of the first stage of labor [between-group differences (B): 80.8 min, 95% confidence interval (CI), 4.18, 157.31, p = 0.03] and decreased duration of the second stage of labor [between-group differences (B): 29.8 min, 95% CI: -55.5, -4.17, p = 0.02] compared to the control group. The exercise group showed greater placental [between-group differences (B): 53.3 g (95% CI: 9.99, 96.7, p = 0.01)] and neonatal [between-group differences (B): 161.8 g (95% CI: 9.81, 313.8, p = 0.033)] weight compared to the control group. No differences between groups were found regarding type of birth (p > 0.05). CONCLUSIONS: A concurrent and supervised physical exercise program during pregnancy is safe and could promote better maternal and neonatal birth-related outcomes. More studies are needed to clarify the mechanisms by which physical exercise increases neonatal and placenta weight.

Effects of a concurrent exercise training program on low back and sciatic pain and pain disability in late pregnancy.

OBJECTIVE: The aim of the present study was to explore the influence of a concurrent exercise (aerobic + resistance) training program, from the 17th gestational week (g.w.) until birth on low back and sciatic pain, and pain disability. A total of 93 pregnant women divided into exercise (n = 49) and control (n = 44) groups followed a 60-min, 3 days/week, concurrent exercise training. METHODS: Low back and sciatic pain were measured with a Visual Analogic Scale (VAS). The disability resulting from pain was assessed with the Oswestry Disability Index (ODI). Measures were performed at the 16th and 34th g.w. RESULTS: The exercise group increased 21.9 mm less the VAS low back (between-group differences (B): 95% CI: -33.6 to -10.2; p < 0.001) and 12.9 mm less the VAS sciatica score (between-group differences: 95% CI (B): -21.8 to -4.0; p = 0.005) than the control group. Regarding the ODI questionnaire, the exercise group increased 0.7, 0.5, and 0.7 less than the control group in pain while sleeping (between-group differences (B): 95% CI: -1.4 to -0.01; p = 0.025), pain while lifting weight (between-group differences (B): 95% CI: -0.9 to -0.01; p = 0.016), and limitations of the social life due to pain (between-group differences(B): 95% CI: -1.3 to -0.06; p = 0.032). Furthermore, the exercise group suffered 6.9% less pain than the control group in the ODI total score (between-group differences (B): 95% CI: -13.9 to 0.053; p = 0.052). CONCLUSION: This concurrent exercise training program adapted to pregnant women improved pain compared to controls.

Association of Mediterranean diet adherence during pregnancy with maternal and neonatal lipid, glycemic and inflammatory markers: The GESTAFIT project.

To examine the association of Mediterranean diet (MD) adherence during pregnancy with maternal and neonatal lipid, glycemic, and inflammatory markers. This study included 152 women from the GESTAFIT trial and a subsample of 35 newborns. The Mediterranean Diet Score, derived from food frequency questionnaires, was employed to assess MD adherence. Total cholesterol, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), triglycerides, and glucose were assessed in the mother (at the 16th and 34th gestational weeks [g.w.]) and in cord arterial and venous serum with standard procedures using an autoanalyzer. Pro-inflammatory and anti-inflammatory cytokines (interleukin [IL]-6, IL-8, IL-10, IL-1beta, interferon gamma, and tumour necrosis factor alpha [TNF-α]) were measured with Luminex xMAP technology. A greater MD adherence was associated with higher HDL-C and lower LDL-C, LDL-C/HDL-C ratio, triglycerides, triglycerides/HDL-C ratio, and TNF-α in the mother at the 16th and the 34th g.w. (|ß|: 0.191-0.388, p < 0.05). A higher intake of whole grain cereals, fruits, vegetables and fish and a lower intake of sweets were associated with higher HDL-C and lower LDL-C, LDL-C/HDL-C ratio, triglycerides, triglycerides/HDL-C ratio, and TNF-α at the 16th and 34th g.w. (|ß|: 0.188-0.334, p < 0.05). No associations were found with the cord arterial and venous serum markers (p > 0.05). A greater MD adherence during pregnancy, driven by a higher intake of whole grain cereals, fruits, vegetables and fish, and a lower intake of sweets, was positively associated with the maternal lipid and inflammatory serum markers throughout gestation. MD adherence during pregnancy was not associated with cord serum markers.

Associations of Mediterranean diet with psychological ill-being and well-being throughout the pregnancy course: The GESTAFIT project.

PURPOSE: The relation between diet and maternal mental health during pregnancy might be relevant to prevent adverse materno-foetal outcomes. This study examined the association of Mediterranean diet (MD) adherence and MD components with mental health during pregnancy. METHODS: This secondary analysis of the GESTAFIT trial included longitudinal data from 152 pregnant women. Dietary habits were assessed with a food frequency questionnaire, and MD adherence was derived from it using the Mediterranean Food pattern. Psychological ill-being (i.e., negative affect, anxiety, and depression) and well-being (i.e., emotional intelligence, resilience, positive affect) were assessed with the Spanish version of well-established self-reported questionnaires. Cross-sectional (16th gestational week [g.w.]) and longitudinal associations (34th g.w.) between MD and mental health were studied using linear regression models. RESULTS: A greater MD adherence was inversely associated with negative affect and anxiety; and positively associated with emotional regulation, resilience and positive affect at the 16th and 34th g.w. (|ß| ranging from 0.179 to 0.325, all p < 0.05). Additionally, a higher intake of whole grain cereals, fruits, vegetables, fish, olive oil and nuts, and a lower intake of red meat and subproducts and sweets were associated with lower negative affect, anxiety, depression and higher emotional regulation, resilience and positive affect throughout gestation (|ß| ranging from 0.168 to 0.415, all p < 0.05). CONCLUSION: A higher intake of whole grain cereals, fruits, vegetables, fish, olive oil and nuts, together with a lower intake of red meat and sweets, resulted in a higher MD adherence, which was associated with a better mental health during pregnancy.

The Protective Role of Physical Fitness on Cardiometabolic Risk During Pregnancy: The GESTAtion and FITness Project.

Physical fitness (PF) is a cornerstone of metabolic health. However, its role in maternal-fetal metabolism during pregnancy is poorly understood. The present work investigates: (i) the association of PF with maternal and fetal cardiometabolic markers, and with clustered cardiometabolic risk during pregnancy, and (ii) whether being fit counteracts cardiometabolic abnormalities associated with overweight/obesity. Several PF components (flexibility, lower and upper body strength, and cardiorespiratory fitness [CRF]) were objectively assessed in 151 pregnant women at gestational weeks 16 and 33, and an overall PF cluster score calculated. At the same times, maternal glycemic and lipid markers, cortisol, and C-reactive protein were assessed with standard biochemical methods, along with blood pressure and a proxy for insulin resistance, and a cardiometabolic risk cluster score determined. These analytes were also measured in maternal and umbilical cord arterial and venous blood collected at delivery. PF was found to be associated with several maternal and a small number of fetal cardiometabolic markers (p < .05). Lower and upper body muscle strength, CRF, overall PF (week 16), and CRF changes (weeks 16-33) were inversely associated with clustered cardiometabolic risk (p < .05). Normal weight fit women had lower values for insulin level, insulin resistance, triglycerides, low-density lipoprotein cholesterol, C-reactive protein, and diastolic blood pressure than did overweight/obese unfit women at week 16 (p < .05). In conclusion, greater PF, especially muscle strength and CRF in early-middle pregnancy, appears to be associated with a better metabolic phenotype, and may protect against maternal cardiometabolic risk. "Keep yourself fit and normal weight before and during early pregnancy" should be a key public health message.

Influence of the degree of adherence to the mediterranean diet and its components on cardiometabolic risk during pregnancy. The GESTAFIT project.

BACKGROUND AND AIMS: Studies regarding dietary patterns and cardiometabolic risk markers during pregnancy are scarce. The aim of the present study was to analyse whether different degrees of adherence to the Mediterranean diet (MD) and the MD components were associated with cardiometabolic markers and a clustered cardiometabolic risk during pregnancy. METHODS AND RESULTS: This study comprised 119 pregnant women from the GEStation and FITness (GESTAFIT) project. Dietary habits were assessed with a food frequency questionnaire at the 16th and 34th gestational weeks (g.w.). The Mediterranean Diet Score was employed to assess MD adherence. The following cardiometabolic markers were assessed: pre-pregnancy body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, triglycerides and high-density lipoprotein cholesterol (HDL-C). A greater MD adherence was associated with a better cardiometabolic status in cross-sectional (16th g.w. and 34th g.w.) and prospective analyses (MD adherence at the 16th g.w. and cardiometabolic markers at the 34th g.w.; SBP, DBP and HDL-C; all, p < 0.05). Participants with the highest MD adherence (Tertile 3) had a lower clustered cardiometabolic risk than those with the lowest MD adherence (Tertile 1) at the 16th and 34th g.w. (both, p < 0.05). A higher intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts were associated with a lower cardiometabolic risk during pregnancy (all, p < 0.05). CONCLUSION: A higher MD adherence, a greater intake of fruits, vegetables and fish and a lower intake of refined cereals and red meat and subproducts showed a cardioprotective effect throughout gestation.

Objectively measured sedentary time and physical activity levels in Spanish pregnant women. Factors affecting the compliance with physical activity guidelines.

The aims of this cross-sectional study were to describe objectively measured sedentary time (ST) and physical activity (PA) levels in Spanish pregnant women, to analyze the degree of compliance with PA guidelines during the early second trimester of pregnancy and to explore sociodemographic and clinical factors associated with meeting these PA guidelines. One hundred and thirty-four Caucasian pregnant women were recruited between October 2015 and October 2017 to participate in this study. Triaxial accelerometers were used to analyze ST andPA levels for seven consecutive valid days. Womenspent512 ± 92.1 minutes daily in sedentary behaviors, and 85 ± 108.2 minutes in moderate-to-vigorous physical activity (MVPA) in bouts of at least 10 minutes. They walked on average 7436 ± 2410steps per day. Only 22% of the study sample complied with the PA guidelines. Having an University degree was related with threefold higher odds of compliance with the PA guidelines (95% confidence interval: 0.096-0.913, p < .05). Binary logistic regressions showed that being primiparous was associated with fivefold higher odds of compliance with the PA guidelines (95% confidence interval 1.658-18.039, respectively, p < .01). Maternal age, BMI, marital status, working status, and previous miscarriages were not associated with compliance with PA guidelines. Pregnant women spent more than a third of the day in sedentary behaviors and the compliance with PA guidelines was less than desirable. Finally, not having an university degree or having children could be factors related to lower odds of compliance with these guidelines, and therefore require special attention from healthcare professionals.

Association of self-reported physical fitness with pain during pregnancy: The GESTAFIT Project.

AIMS: To explore the association of self-reported physical fitness with bodily, lumbar and sciatic pain, and pain disability during pregnancy. METHODS: The present study sample comprised 159 pregnant women (32.9 ± 4.7 years old). Self-reported physical fitness was assessed with the International Fitness Scale (IFIS), where higher scores indicate greater physical fitness. Bodily pain was assessed with the 36-Item Short Form Health Survey (SF-36), where higher scores indicate lower pain. Lumbar and sciatic pain were measured with a visual analogue scale (VAS). The Oswestry Disability Index (ODI) questionnaire was employed to assess the disability resulting from pain. Measures were assessed at 16th and 34th gestational weeks (g. w.). RESULTS: Pregnant women showed low-moderate pain during pregnancy course. Most of them showed medium self-reported overall physical fitness. At 16th g. w., greater self-reported overall physical fitness and cardiorespiratory fitness were associated with less bodily and lumbar pain, and pain disability (all, P < 0.05). Greater muscular strength was associated with less bodily pain and pain disability (both, P < 0.05). Greater speed-agility was associated with less bodily pain (P < 0.01) and less pain disability (P < 0.05). Self-reported flexibility was not associated with any outcome (P > 0.05). At 34th g. w., greater overall physical fitness and its components were associated with less bodily and sciatic pain (all, P < 0.05). CONCLUSION: Greater self-reported overall physical fitness and its components are associated with less bodily, lumbar and sciatic pain, and reduced pain disability during pregnancy. Future studies are needed to explore whether increasing physical fitness before and during pregnancy could decrease pain in this relevant stage.

Association of sedentary time and physical activity during pregnancy with maternal and neonatal birth outcomes. The GESTAFIT Project.

AIM: (a) To analyse the association of objectively measured sedentary time (ST) and physical activity (PA) during early second trimester of pregnancy with maternal and neonatal birth outcomes; (b) to explore if ST and PA differ between women with vaginal or caesarean section deliveries. METHODS: Ninety-four Caucasian pregnant women (32.9 ± 4.6 years old) participated in this prospective longitudinal study. Triaxial accelerometers were used to assess ST and PA intensity levels for seven consecutive days during second trimester of pregnancy. Birth data were collected from the obstetric medical records. Umbilical cord arterial and venous blood gas (pH, partial pressure of carbon dioxide and oxygen, and oxygen saturation) were analysed after birth. RESULTS: After adjusting for potential confounders, greater ST was associated with higher arterial and venous cord blood partial pressure of carbon dioxide and more acidic arterial and venous pH (all, P < 0.01). Moderate PA, moderate-to-vigorous PA (MVPA), total PA and steps per day were positively associated with arterial cord blood oxygen saturation (all P < 0.05). Steps per day were inversely associated with gestational age at birth (P < 0.01), and duration of first stage of labor (P < 0.05). Total and light PA were associated with a more alkaline pH in umbilical vein (all, P < 0.01). Vigorous PA was inversely associated with the Apgar score (P < 0.01). No significant differences were observed in ST and PA levels between women with vaginal and women with caesarean section deliveries (all, P > 0.10). CONCLUSION: Increasing PA and decreasing ST during pregnancy might promote better maternal and neonatal birth markers.

Mediterranean Diet Adherence and Health-Related Quality of Life during Pregnancy: Is the Mediterranean Diet Beneficial in Non-Mediterranean Countries?

This study aimed to examine the association of Mediterranean diet (MD) adherence and MD components with health-related quality of life (HRQoL) in pregnant women from Spain and Sweden. A total of 138 pregnant women from Spain (age: 32.9 ± 4.6 years old) and 302 pregnant women from Sweden (age: 31.3 ± 4.1 years old) were included. MD adherence was assessed with the Mediterranean food pattern (i.e., a MD index) at the 14-16th gestational weeks. HRQoL was assessed with the Spanish and Swedish versions of the 36-item Short-Form Health Survey (SF-36 and RAND-36, respectively) at the 14-16th and 34-37th gestational weeks. A greater MD adherence was associated with better physical functioning, bodily pain, vitality, emotional role, and mental health in cross-sectional associations (2nd trimester) in the Spanish sample (all p < 0.05). Furthermore, a greater MD adherence was associated with lower bodily pain in both Spanish and Swedish samples (both p < 0.05) in the 3rd trimester. The associations of MD adherence with pain seem to be explained by a greater intake of fiber, fish, fruits, nuts, and legumes (all p < 0.05). A greater MD adherence, driven by a higher intake of fiber, fish, fruits, nuts, and legumes, was associated with lower pain throughout pregnancy in both Mediterranean and non-Mediterranean populations.

Influence of a Concurrent Exercise Training Program on Health-Related Quality of Life During Advanced Pregnancy: The GESTAFIT Project.

BACKGROUND: Health-related quality of life (HRQoL) may be altered during pregnancy due to pregnancy-related changes in all domains of women's health. HYPOTHESIS: A supervised concurrent exercise-training program from the 17th gestational week until birth positively influences HRQoL. STUDY DESIGN: Randomized controlled trial. LEVEL OF EVIDENCE: Level 1. METHODS: Eighty-six pregnant women (age, 33.1 ± 4.6 years; prepregnancy body mass index, 23.5 kg/m2), divided into exercise (n = 41) and control (n = 45) groups, participated in this study (per-protocol basis). The exercise group followed a 60-min, 3 days/week, concurrent (aerobic + resistance) exercise training program. HRQoL was assessed with the 36-Item Short Form Health Survey (SF-36), where higher scores (0-100) indicate better HRQoL. RESULTS: After adjusting for potential confounders, the exercise group decreased 16.1 points less than the control group in the SF-36 physical functioning domain [between-group differences (B): 95% confidence interval (CI), 9.02 to 23.22; P < 0.01], and 4.5 points less in the SF-36 physical component summary than the control group (between-group differences (B): 95% CI, 0.65 to 8.28; P = 0.02). Intention-to-treat basis analyses depicted similar results, where the exercise group decreased 10.03 points less than the control group the in the SF-36 social functioning domain (between-group differences (B): 95% CI, 0.39 to 19.68; P = 0.04). CONCLUSION: A supervised concurrent exercise training program ameliorates HRQoL decreases along gestation. Although HRQoL decreased throughout pregnancy in both groups, this impact was less in the exercise group, especially in the SF-36 physical functioning, the SF-36 social functioning, and the SF-36 physical component summary. CLINICAL RELEVANCE: Healthcare providers may encourage pregnant women to exercise in this physiological stage for a better HRQoL throughout pregnancy.

Assessing the Mediterranean diet adherence during pregnancy: Practical considerations based on the associations with cardiometabolic risk.

OBJECTIVE: The aim of the present study was to provide practical considerations for assessing MD adherence during pregnancy based on the association with cardiometabolic risk. STUDY DESIGN: Longitudinal study. MAIN OUTCOME MEASURES: A food frequency questionnaire was fulfilled by 152 pregnant women at the 16th gestational week (g.w.). We calculated the Mediterranean Food Pattern (MFP), the MD Scale (MDScale), the Short MD questionnaire (SMDQ), the MD Score (MedDietScore), and the MD scale for pregnant women (MDS-P). The cardiometabolic risk score consisted of pre-pregnancy body mass index, blood pressure, glucose, triglycerides, and high-density lipoprotein-cholesterol (at 16th and 34th g.w.). RESULTS: Multiple linear regression models showed that the MFP, the MedDietScore, and the SMDQ were associated with lower cardiometabolic risk at the 16th and 34th g.w. (ß's: -0.193 to -0.415, all p < 0.05); and the MDS-P at the 34th g.w. (ß = -0.349, p < 0.01). A comparison of these models with the J test showed that the MFP and the MedDietScore outperformed the SMDQ at the 16th g.w. (p's < 0.05); while the MedDietScore outperformed the SMDQ, MFP, and MDS-P (p's < 0.05) at the 34th g.w. Receiver-Operating-Characteristic-derived thresholds for the MFP, MedDietScore and MDS-P indices were 21, 30, and 6 points, respectively, to identify women with high cardiometabolic risk. CONCLUSION: The MFP and MedDietScore are recommended to assess MD adherence during pregnancy, as these showed the strongest associations with cardiometabolic risk. Our validated thresholds might assist in the detection of poor dietary patterns during pregnancy.

Physical fitness and maternal body composition indices during pregnancy and postpartum: the GESTAFIT project.

We explored the association of physical fitness (PF) during pregnancy with maternal body composition indices along pregnancy and postpartum period. The study comprised 159 pregnant women (32.9 ± 4.7 years old). Assessments were carried out at the 16th and 34th gestational weeks (g.w.) and six weeks postpartum. Cardiorespiratory fitness (CRF), muscular strength (absolute and relative values) and flexibility were measured. Body composition indices were obtained by using dual-energy X-ray absorptiometry at postpartum. The results, after adjusting for potential covariates at the 16th g.w., indicated that greater CRF was associated with lower postpartum indices total fat mass, android and gynoid fat mass (all, p < 0.05). Greater absolute upper-body muscular strength was associated with greater pre-pregnancy body mass index (BMI), gestational weight gain (GWG); and postpartum indices body weight, BMI, lean mass, fat free mass, fat mass, gynoid fat mass, T-score and Z-score bone mineral density (BMD) (all, p < 0.05). Greater upper-body flexibility was associated with lower pre-pregnancy BMI; and postpartum indices body weight, BMI, lean mass, fat free mass, fat mass, android fat mass and gynoid fat mass, and with greater GWG (all, p < 0.05). At the 34th g.w., greater CRF was additionally associated with greater postpartum T-score and Z-score BMD (both, p < 0.05). In conclusion, this study reveals that greater PF levels, especially during early pregnancy, may promote a better body composition in the postpartum period. Therefore, clinicians and health promoters should encourage women to maintain or improve PF levels from early pregnancy.

Given that obesity is on the rise today, it is important to find strategies to cope with it, especially during pregnancy.The results of the present study suggest that greater physical fitness during early pregnancy is key to promoting better body composition in the postpartum period.It should be of clinical interest to encourage pregnant women to maintain or improve their physical fitness levels.

Influence of a concurrent exercise training program during pregnancy on the placenta mitochondrial DNA integrity and content of minerals with enzymatic relevance. The GESTAFIT project.

INTRODUCTION: We aimed i) to investigate the effects of a concurrent (aerobic plus strength) exercise intervention during pregnancy on placental mtDNA copy number, proportion of deleted mtDNA, and on the content of some trace and ultra-trace minerals with coenzymatic relevance; ii) to explore the association of such mitochondrial markers with the concentration of these minerals. METHODS: For the present study specific aims, 47 placentas were randomly selected from women that participated in the GESTAFIT project into exercise (n = 24) or control (n = 23) groups. The exercise group followed a concurrent aerobic and strength training program, three 60-min sessions/week, from the 17th gestational week until birth. Placenta tissue was collected and processed for minerals determination by the inductively coupled plasma mass spectrometry technique. RT-PCR was used to determine placentas mtDNA copy number and ND1/ND4 deletion. RESULTS: After adjusting for potential confounders, the mothers who participated in the exercise program had placentas with greater mtDNA copy number (p = 0.04) and lower mtDNA deletion (p = 0.003). Placentas from mothers in the exercise group presented higher manganese content than those from the controls (0.26 ± 0.03 mg/dL vs. 0.13 ± 0.03 mg/dL, p = 0.003). Placenta manganese content was significantly associated with lower mtDNA deletions (r = -0.382) and greater mtDNA copy number (r = 0.513). Iron content was associated with higher mtDNA copy number (r = 0.393). Selenium content was associated with lower mtDNA deletion (r = -0.377) and greater mtDNA copy number (r = 0.442). Finally, zinc and magnesium content were associated with higher mtDNA copy number (r = 0.447 and r = 0.453, respectively). DISCUSSION: This concurrent exercise training program induced a better placental status, which might be mediated through an improvement of mitochondrial bioenergetics and antioxidative capacity.

Influence of an exercise intervention plus an optimal Mediterranean diet adherence during pregnancy on the telomere length of the placenta. The GESTAFIT project.

We aimed to investigate whether the effects of exercise on placental relative telomere length (RTL) after delivery are modulated by the Mediterranean diet [MD] adherence in 65 pregnant women (control n = 34, exercise n = 31). No differences were found in placental RTL between the exercise and the control groups (p = 0.557). The interaction-term between exercise and MD adherence with placental RTL was significant (p = 0.001). Specifically, women in the exercise group showed longer placental RTL after birth compared to controls (referent group), only for those women with a high MD adherence (mean difference = 0.467, p=0.010). A concurrent-exercise training plus an optimal MD adherence during pregnancy might prevent the placental RTL shortening.

A 16-week multicomponent exercise training program improves menopause-related symptoms in middle-aged women. The FLAMENCO project randomized control trial.

OBJECTIVE: To investigate the influence of a supervised multicomponent exercise training program on menopause-related symptoms, particularly vasomotor symptoms (VMS), in middle-aged women. METHODS: A total of 112 middle-aged women (mean age 52 ± 4 y old, age range 45-60 y) from the FLAMENCO project (exercise [n = 59] and counseling [n = 53] groups) participated in this randomized controlled trial (perprotocol basis). The exercise group followed a multicomponent exercise program composed of 60-minute sessions 3 days per week for 16 weeks. The 15-item Cervantes Menopause and Health Subscale was used to assess the frequency of menopause-related symptoms. RESULTS: After adjusting for body mass index and Mediterranean diet adherence, the subscales measuring menopause-related symptoms and VMSs decreased 4.6 more in the exercise group compared to the counseling group (between-group differences [B]: 95% CI: -8.8 to -0.2; P  = 0.040). The exercise group also showed significant improvements in the subscales of couple relationships (between-group differences [B]: -1.87: 95% CI: -3.29 to - 0.45; P  = 0.010), psychological state (between-group differences [B]: -2.3: 95% CI: -5 to -0.2; P  = 0.035), and VMSs (between-group differences [B]: -4.5: 95% CI: -8.8 to -0.2; p  = 0.040) in the Cervantes Menopause and Health Subscale compared with the counseling group. CONCLUSIONS: A 16-week multicomponent physical exercise program showed a positive effect on menopause- related symptoms especially in couple relationships, psychological state, and VMS, among 45 to 60 year old women.

Associations between Sociodemographic Factors, Lifestyle Behaviors, Pregnancy-Related Determinants, and Mediterranean Diet Adherence among Pregnant Women: The GESTAFIT Project.

We examined sociodemographic factors, lifestyle behaviors, and pregnancy-related determinants associated with adherence to the Mediterranean diet (MD) during pregnancy. A total of 152 Caucasian pregnant women were included in this cross-sectional study. Dietary habits and MD adherence were assessed with a food frequency questionnaire. Physical activity (PA) levels and physical fitness (PF) components (cardiorespiratory fitness, relative muscle strength, and flexibility) were objectively measured. A clustered overall PF index was calculated. Participants with a high MD adherence were older, had a lower body mass index (BMI), spent more time in moderate−vigorous PA, had a greater overall PF, cardiorespiratory fitness, and relative muscle strength compared to participants with low MD adherence (all, p < 0.05). When we explored factors associated with improved MD adherence with logistic regression analysis, we found that the following factors: lower pre-pregnancy BMI (OR = 2.337; p = 0.026), meeting PA recommendations (OR = 2.377; p = 0.045), higher relative muscle strength (OR = 2.265; p = 0.016), and higher overall PF (OR = 5.202; p = 0.004) increased the chances to adhere to the MD. Older age, lower BMI, greater PF, and meeting PA recommendations were associated with higher MD adherence. These factors should be considered for a better design of educational programs and guidelines focused on improving materno−fetal health status during pregnancy.

Exercise, Mediterranean Diet Adherence or Both during Pregnancy to Prevent Postpartum Depression-GESTAFIT Trial Secondary Analyses.

Targeting lifestyle behaviors during pregnancy is crucial to prevent the highly prevalent postpartum depression and its consequences. In these secondary analyses of an intervention trial to investigate the effects of concurrent exercise training on postpartum depression, we aimed to investigate the potential role of Mediterranean diet (MD) adherence on the exercise effects. A total of 85 pregnant women met the per-protocol criteria (exercise n = 46, control n = 39). The exercise program was delivered in 60 min sessions, 3 days/week, from the 17th gestational week until birth. Women's dietary habits were assessed with a food frequency questionnaire. The Mediterranean Food Pattern (an MD index) was derived from it to assess MD adherence. We used the Edinburgh Postnatal Depression Scale to assess postpartum depression. The postpartum depression score was not statistically different between control and exercise groups (p > 0.05). A higher consumption of fruits (ß = -0.242, p = 0.022), lower intake of red meat and subproducts (ß = 0.244, p = 0.020), and a greater MD adherence (ß = -0.236, p = 0.027) were associated with lower levels of postpartum depression. Greater adherence to the MD during pregnancy was associated with fewer depressive symptoms and a lower risk of postpartum depression. Postnatal depression was not reduced by prenatal exercise. Promoting fruit consumption while controlling the intake of red meat during pregnancy might prevent postnatal depression.

Differences in maternal and neonatal cardiometabolic markers and placenta status by foetal sex. The GESTAFIT project.

AIMS: To explore the differences in some maternal-neonatal metabolic markers and placenta status by foetal sex. METHODS: One hundred thirty-nine Caucasian pregnant women from the GESTAFIT project and their new-borns were included in the present cross-sectional study. Serum cardiometabolic markers (i.e. lipid and glycaemic profile and uric acid) were analysed at late pregnancy and at birth. In placenta, telomeres length, proportion of deleted mitochondrial-DNA and mitochondrial-DNA density, some minerals and interleukin 8, epidermal growth factor, fibroblast growth factor-2 and vascular endothelial growth factor were measured. The study was run between November 2015 and April 2018. RESULTS: Mothers carrying a male showed higher serum triglycerides than mothers carrying a female at late pregnancy (p < .05). Serum total and low-density lipoprotein cholesterol were greater in males' umbilical cord blood artery compared to females' new-borns (both, p < .05). Mothers of males and male new-borns presented higher uric acid than mothers of females and female new-borns at birth (p < .05). Female's placentas presented greater placental-newborn weight ratio, manganese content and fibroblast growth factor-2 (all, p ⩽ .05), and evidence of statistical significance in telomeres length, which were 17% longer (p = .076). CONCLUSION: Our findings show weak differences in some cardiometabolic and placental status markers by foetal sex. Notwithstanding, we observed a slightly more proatherogenic profile in both, mothers carrying males' foetuses and male new-borns. We also found lower serum uric acid and better placenta status in mothers carrying a female. These findings indicate that foetal sex might need to be considered for a more personalized follow-up of pregnancies.

Premenstrual and menstrual changes reported after COVID-19 vaccination: The EVA project.

BACKGROUND: Menstrual disorders were not reported as a possible secondary effect in any of the clinical trials for the SARS-CoV-2 vaccines. AIM: To describe the prevalence of perceived premenstrual and menstrual changes after COVID-19 vaccine administration. DESIGN: Cross-sectional study. METHODS: A total of 14,153 women (mean age 31.5 ± 9.3 years old) who had received the full course of vaccination at least three months earlier were included in this cross-sectional study. Data including the type of vaccine administered, perceived changes in the amount and duration of menstrual bleeding, presence of clots, cycle length, and premenstrual symptoms were collected through a retrospective online survey from June to September 2021. RESULTS: Of the women who participated in this study, 3136 reported no menstrual changes and 11,017 (78% of the study sample) reported experiencing menstrual cycle changes after vaccination. In summary, women who reported menstrual changes after vaccination were older (overall p < 0.001) and slightly more smokers (p = 0.05) than women who did not report any changes. The most prevalent changes in relation to premenstrual symptoms were increased fatigue (43%), abdominal bloating (37%), irritability (29%), sadness (28%), and headaches (28%). The most predominant menstrual changes were more menstrual bleeding (43%), more menstrual pain (41%), delayed menstruation (38%), fewer days of menstrual bleeding (34.5%), and shorter cycle length (32%). CONCLUSION: Women vaccinated against COVID-19 usually perceive mild menstrual and premenstrual changes. Future studies are warranted to clarify the physiological mechanisms behind these widely reported changes.
