“…Santa Cruz is located in the countryside, 122 km from Natal and has approximately 39,660 inhabitants. This article presents a secondary analysis of data from a research study that aimed to examine the influence of menopause and hormone levels on sarcopenia and physical function (Azevedo et al, 2018;Câmara et al, 2015a). Data were collected between 2014 and 2016.…”

Background Self-rated Health (SRH) is regarded as a simple and valid measure of a person’s health status, given its association to adverse health outcomes, including low physical performance in older populations. However, studies investigating these associations in low- and middle-income settings are scarce, especially for middle-aged populations. Understanding the validity of SRH in relation to objective health measures in low-income populations could assist in decision making about health policy and strategies, especially in under-resourced settings. Objective Assess the relationship between SRH and physical performance measures in middle-aged and older women in a low-income setting of Brazil. Methods This is a cross-sectional study of 571 middle-aged (40–59 years old) and older (60–80 years old) women living in Parnamirim and Santa Cruz in the Northeast region of Brazil. Participants reported their health status and were allocated to the “SRH good” or “SRH poor” groups. The physical performance evaluation included: handgrip strength, one-legged balance with eyes open and closed and chair stand test. The relationship between SRH and physical performance for middle-aged and older women was assessed by quantile regression (modeling medians) adjusted for potential confounders (age, socioeconomic variables, body mass index, menopause status, age at first birth, parity, chronic conditions and physical activity). Results Middle-aged women from the “SRH good” group presented better physical performance with 1.75 kgf stronger handgrip strength (95% CI [0.47–3.02]; p = 0.004), 1.31 s longer balance with eyes closed ([0.00–2.61]; p = 0.030), and they were 0.56 s faster in the chair stand test ([0.18–0.94]; p = 0.009) than those who reported “SRH poor”. No association was found for balance with eyes open. For older women, there was no evidence of associations between physical performance and SRH. Conclusion This study showed that SRH is significantly associated with objective measures of physical performance in a sample of low-income middle-aged women. SRH can be an important tool to indicate the need for further evaluation of physical performance among middle-aged women and can be particularly useful for low-income communities.

“…Moreover, among the aforementioned studies, only one determined plethysmographic LFD [6]. Other studies evaluated the impacts of parity on respiratory muscle strength [17, 21] and physical function [18, 30] of healthy females, and some others included females with chronic diseases [ eg , COPD [20], protease inhibitor phenotype [19], diabetes [31] and sleep-apnea syndrome [29]]. This study showed that the G 2 compared to the G 1 , and C 2 or C 3 compared to C 1 , had a tendency towards lung-hyperinflation.…”

“…Clinical data were collected using the ATS questionnaire [28], widely described elsewhere [8, 10, 24]. Parity, defined as the number of offspring a female has borne, was introduced in three forms: numerical (unit), two groups [G 1 (parity ≤ 6); G 2 (parity > 6)] and three classes [C 1 : 1 ≤ parity ≤ 4; C 2 : 5 ≤ parity ≤ 8; C 3 : parity ≥ 9] [17, 29–31]. Menopausal status was determined using the stages of reproductive aging workshop classification [32].…”

BackgroundStudies evaluating the impacts of parity on LFD of healthy females presented controversial conclusions.AimTo compare the LFD of healthy females broken down according to their parities.MethodsA medical questionnaire was administered and anthropometric data were determined. Two groups [G1 (n = 34): ≤ 6; G2 (n = 32): > 6] and three classes [C1 (n = 15): 1–4; C2 (n = 28): 5–8; C3 (n = 23): 9–14] of parities were identified. LFD (plethysmography, specific airway resistance (sRaw)] were determined. Student’s t-test and ANOVA test with post-Hoc test were used to compare the two groups’ and the three classes’ data.ResultsG1 and G2 were age and height matched; however, compared to G1, G2 had a lower body mass index (BMI). C1, C2 and C3 were height, weight and BMI matched; however, compared to C2, C3 was older. G1 and G2 had similar values of FEV1, forced- and slow- vital capacities (FVC, SVC), maximal mid-expiratory flow (MMEF), forced expiratory flow at x% of FVC (FEFx%), peak expiratory flow (PEF), expiratory and inspiratory reserve volumes (ERV, IRV, respectively), inspiratory capacity (IC), sRaw, FEV1/FVC, FEV1/SVC, and residual volume/total lung capacity (RV/TLC). The three classes had similar values of MMEF, FEFx%, PEF, thoracic gas volume (TGV), ERV, IRV, FEV1/FVC, FEV1/SVC and RV/TLC. Compared to G1, G2 had higher TGV (2.68±0.43 vs. 3.00±0.47 L), RV (1.80±0.29 vs. 2.04±0.33 L) and TLC (4.77±0.62 vs. 5.11±0.67 L). Compared to C1, C2 had higher FEV1 (2.14±0.56 vs. 2.47±0.33 L), FVC (2.72±0.65 vs. 3.19±0.41 L), SVC (2.74±0.61 vs. 3.24±0.41 L), TLC (4.47±0.59 vs. 5.10±0.58 L), IC (1.92±0.41 vs. 2.34±0.39 L) and sRaw (4.70±1.32 vs. 5.75±1.18 kPa*s). Compared to C1, C3 had higher TLC (4.47±0.59 vs. 5.05±0.68 L) and RV (1.75±0.29 vs. 2.04±0.30 L).ConclusionIncreasing parity induced a tendency towards lung-hyperinflation.

“…These hormonal alterations cause a decrease in muscle strength, decreased relaxation of bronchial smooth muscle and increased compression of the thoracic spine due to osteoporosis, directly interfering with the functioning of the pulmonary system [ 10 ]. Still related to women’s health particularities, there is also evidence that multiparity is related to limited inspiratory strength, where the higher the number of pregnancies, the lower the values of maximal inspiratory pressure [ 12 ]. All these aspects show how inspiratory muscles strength may be influenced by different female health variables and could be associated with others.…”

“…Although there is certain evidence in the literature that increasing the efficiency of respiratory muscles improves postural balance in elderly people [ 17 – 20 ], few investigations have been carried out considering the relationship between postural balance and objective measurements (such as maximal respiratory pressures) of muscle strength in exclusively female populations [ 17 , 21 ] associated with functions altered by the changes occurring during the aging process, and in addition to the subject’s reproductive history [ 11 , 12 , 15 ]. So, it is of extreme importance to develop research in this specific field in order to direct the assessments and consequently, the treatments for this population, considering objective evaluation techniques.…”

Background There is scarce evidence on changes at the functional level associated with the respiratory area in women. This study aims to analyse the relationship between inspiratory muscle strength and balance in women. Material and methods In this cross-sectional observational study, the sample consisted of groups according to the results obtained in the balance test. Inspiratory muscle weakness was defined as maximum inspiratory pressure (MIP) ≤ 80% of the predictive value. MIP was carried out using through a mouthpiece, with an electronic manometer. Logistic regression model was used to examine if MIP predicts balance. Results 159 women participated in the study. Approximately 20% of them achieved balance ≤ 2 seconds and 18% presented MIP≤80%. MIP was associated with the time achieved in the one-leg support test. Subjects with MIP ≤ 80% of the predictive value show 3 times more risk of having a lower performance in the balance test (OR = 3.26). Conclusions Inspiratory muscle weakness is associated with deficient balance in this sample. It shows the need for multidimensional assessment and rehabilitation strategies for patients identified as having MIP weakness and/or balance disorders.
