Scores on the stress scale and alcohol intake support the concept that PMS is stress related; intervention strategies to cope with stress may be effective. Further study will be required to determine the influence of race on PMS and whether women with PMS exercise more regularly than women without PMS because they believe exercise is effective in attenuating their symptoms.

This data provided evidence that obesity is strongly associated with PMS. Since obesity is a modifiable risk factor, PMS management strategies should not only consider factors such as, high stress, and smoking but also obesity.

Perimenstrual breast pain (cyclical mastalgia) is a common problem that can be sufficiently severe to interfere with usual activities, and has been associated with elevated mammography usage in young women. This study was undertaken to replicate clinic-based research on cyclical mastalgia, and to examine the association between this disorder and health-related behaviors and perceived stress. Using random digit dialing throughout Virginia, 874 women aged 18-44 were interviewed. Sixty-eight per cent of women experienced cyclical breast symptoms; 22% experienced moderate to extreme discomfort (classified as cyclical mastalgia). Hormonal contraceptive usage was associated with significantly less mastalgia and premenstrual syndrome (PMS). Smoking, caffeine consumption and perceived stress were associated with mastalgia (odds ratios = 1.52, 1.53 and 1.7, respectively). Young women (under 35 years) with mastalgia were more likely to have had a mammogram (20.2%) than those without mastalgia (9.9%). Most women with this disorder (77.5%) did not have PMS. The prevalence of cyclical mastalgia and its association with mammography replicate clinic-based findings. Associations with smoking and stress had not previously been reported. Prospective research is needed to determine the biopsychosocial factors contributing to this disorder.

ObjectiveTo quantify the current weight of evidence of the association between overweight and obesity as risk factors for COVID-19-related hospitalisations (including hospital admission, intensive care unit admission, invasive mechanical ventilation) and death, and to assess the magnitude of the association and the potential dose–response relationships.DesignPubMed, Embase, Cochrane, Web of Sciences, WHO COVID-19 database and Google Scholar were used to identify articles published up to 20 July 2021. Peer-reviewed studies reporting adjusted estimates of the association between overweight or obesity and COVID-19 outcomes were included. Three authors reviewed the articles and agreed. The quality of eligible studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. Random-effects meta-analysis was used to estimate the combined effects.ResultsA total of 208 studies with 3 550 997 participants from over 32 countries were included in this meta-analysis. Being overweight was associated with an increased risk of COVID-19-related hospitalisations (OR 1.19, 95% CI 1.12 to 1.28, n=21 studies), but not death (OR 1.02, 95% CI 0.92 to 1.13, n=21). However, patients with obesity were at increased risk of both COVID-19-related hospitalisations (OR 1.72, 95% CI 1.62 to 1.84, n=58) and death (OR 1.25, 95% CI 1.19 to 1.32, n=77). Similarly, patients with extreme obesity were at increased risk of COVID-19-related hospitalisations (OR 2.53, 95% CI 1.67 to 3.84, n=12) and death (OR 2.06, 95% CI 1.76 to 3.00, n=19). There was a linear dose–response relationship between these obesity categories and COVID-19 outcomes, but the strength of the association has decreased over time.ConclusionBeing overweight increases the risk of COVID-19-related hospitalisations but not death, while obesity and extreme obesity increase the risk of both COVID-19-related hospitalisations and death. These findings suggest that prompt access to COVID-19 care, prioritisation for COVID-19 vaccination and other preventive measures are warranted for this vulnerable group.

Previous abortion is a significant risk factor for LBW and PB, and the risk increases with the increasing number of previous abortions. Practitioners should consider previous abortion as a risk factor for LBW and PB.
