AI Article Synopsis
- The study examined how the menstrual cycle affects taste preferences and food habits in 8 women (6 smokers, 2 non-smokers) aged 23-37.
- It measured hormone levels (oestradiol and progesterone) and taste sensitivities for sweet, bitter, salty, and sour during different menstrual cycle days.
- Results showed increased sensitivity to sweet tastes with higher oestradiol and to bitter with higher progesterone, while food consumption varied mainly in meat and fruit, with a decrease in energy intake correlated with peak oestradiol levels.
Article Abstract
Gustatory and food habit changes during the menstrual cycle were studied in 8 women, 6 smokers and 2 non-smokers, aged 23-37 years. The following parameters were evaluated during three consecutive menstrual cycles: blood oestradiol and progesterone levels on the 7th, 14th and 21st day of each cycle (radioimmunoassay); detection and recognition thresholds and concentration preferences for sucrose, sodium chloride, citric acid and quinine sulphate on the 1st, 7th, 14th and 21st day of each cycle; food consumption (weighed record) on days 1 and 2, 6-8, 13-15 and 20-22 each cycle. The four basic tastes were influenced differently by blood hormone levels during the menstrual cycle. Sensitivity to sweet taste increased with an increase of oestradiol, while sensitivity to bitter taste increased with an increase of progesterone. No correlations between hormone levels and acid taste, and only a few correlations for salt taste were found. Food habits changed during the cycle particularly for meat and fruit. Vegetables and cereals showed only a tendency to vary. In correspondence with the highest oestradiol values there was a tendency towards lower energy intake, -122 kcal (-0.51 MJ) = 8%, predominantly provided by carbohydrates (as bread).

National Institute of Health, Cheongju, Republic of Korea.
Objectives: We examined the health-related quality of life (HRQoL) during menopause transition (MT) among middle-aged Korean women.
Methods: This cross-sectional study comprised 2,290 middle-aged women who completed web-based questionnaires between 2020 and 2022. Based on self-reported menstrual cycle patterns, menopause status was classified as premenopausal, early or late transition, or postmenopausal.
Dysmenorrhea, Premenstrual Syndrome, and Lifestyle Habits in Young University Students in Spain: A Cross-Sectional Study.

Background: Menstruation is a physiological process that may be accompanied by pain, headache, edema, emotional changes, and other symptoms, all of which affect quality of life. Although the results of some studies indicate lifestyle habits can affect the menstrual cycle and associated symptoms, few have investigated this issue, and even fewer have explored the impact of these symptoms on quality of life, in Spanish women.
Purpose: The objectives of this study were to determine the prevalence of dysmenorrhea and premenstrual syndrome (PMS) among students at a Spanish university, assess the impact of these conditions on quality of life, and analyze the relationship among lifestyle habits, dysmenorrhea, and PMS.
Consensus recommendations for measuring the impact of contraception on the menstrual cycle in contraceptive clinical trials.

MSI Reproductive Choices, London, England, United Kingdom.
Objective: We sought to develop consensus recommendations for measurement and analysis of data on contraceptive-induced menstrual changes (CIMCs) in contraceptive clinical trials. We built upon previous standardization efforts over the last 50 years and prioritized input from a variety of global experts and current regulatory authority guidance on patient-reported outcomes.
Study Design: We completed a formal consensus-building process with an interdisciplinary group of 57 experts from 30 organizations and 14 countries in five global regions who work across academia, nonprofit research organizations, the pharmaceutical industry, and funding agencies.

Menstrual pain affects women's quality of life and productivity, yet objective molecular markers for its severity have not been established owing to the variability in blood levels and chemical properties of potential markers such as plasma steroid hormones, lipid mediators, and hydrophilic metabolites. To address this, we conducted a metabolomics study using five analytical methods to identify biomarkers that differentiate menstrual pain severity. This study included 20 women, divided into mild (N = 12) and severe (N = 8) pain groups based on their numerical pain rating scale.

Background: Menstrual cycle characteristics are potential indicators of hormonal exposures and may also signal cardiovascular disease risk factors, both of which are relevant to cognitive health. However, there is scarce epidemiological evidence on the association between cycle characteristics and cognitive function.
Objectives: We studied the associations of menstrual cycle characteristics at three stages of a woman's reproductive lifespan with cognitive function in midlife.
