ABSTRACT

We examine the effect of COVID-19-induced lockdown on the profitability of listed firms in India. We use quarterly income statement of 4168 listed firms for the period between April–June 2020 quarter and April–June 2022 quarter and compare their financial data with previous quarters (2015–2019). Using a difference-in-difference estimation framework and various profitability measures, we find that the COVID-19 lockdown has reduced profits by around 15 per cent for listed firms in India. Our results are robust to various robustness tests and alternate specifications. We find evidence of firms losing revenues more than expenses, thus leading to decline in profits. The main effect is conditioned by firm-specific factors. Specifically, firms that are smaller, older, unlisted and that do not belong to any group witnessed larger decline in profitability due to lockdown. Additionally, the effect of lockdown is more pronounced in areas that had lower mobility and higher COVID-19 spread. These results underscore the importance of institutional factors and pre-existing firm characteristics in conditioning the impact of lockdown on firm profitability. © 2023 The Economic Society of Australia.

ABSTRACT

Relevance: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age. The prevalence rates of PCOS depend on the diagnostic criteria used and the characteristics of the population sample, and in the general population of women of reproductive age, the prevalence of the syndrome ranges from 6-9% to 19.9% [1,2]. According to modern criteria adopted by the consensus in Rotterdam, then systematically updated by ESHRE / ASRM (2014), the presence of two of the three criteria in a patient simultaneously allows to diagnose PCOS if other pathological conditions are excluded (thyroid pathology, congenital adrenal hyperplasia, adrenogenitalsyndrome, androgen-secreting tumors, Itsenko-Cushing syndrome). Modern international diagnostic criteria include the following signs: (1) signs of polycystic ovaries according to information from pelvic ultrasound investigation (the presence of more than 10 follicles in each ovary);(2) oligo-anovulation;(3) clinical (presence of hirsutism) or biochemical (increased androgen levels) development of ovarian hyperandrogenism [3, 4]. Polycystic ovary syndrome is closely related to many diseases, including metabolic syndrome. Although insulin resistance is an important risk factor for metabolic syndrome and other diseases associated with PCOS, hyperandrogenismmay also be an independent risk factor for type 2 diabetes, obesity, cardiovascular disease (CVD), and metabolic syndrome in female patients. Obesity is the most common symptom in PCOS patients (33-88%), which has a large impact on fertility and can lead to adverse effects such as menstrual irregularities, anovulation, infertility and abortion. Therefore, weight management in early PCOS is essential to improve fertility and quality of life. Hyperandrogenism plays a decisive role in abdominal obesity in obese women during adolescence, adulthood and menopause [5]. Although some studies have shown a negative association between plasma androgen levels (A4, DHEA and DHEAS) and obesity [6,7]. But the mechanism of how androgens affect fat cells in women is poorly understood. A number of observations show that among obese women with PCOS, metabolic disorders associated with insulin resistance and obesity, in many cases, play a more important role in the mechanism of anovulation in PCOS than excess androgens. In recent years, it has been established that in PCOS there is a frequent combination of hyperandrogenism and insulin resistance. With insulin resistance, there is a decrease in the response of insulin-sensitive tissues to the hormone insulin with its sufficient level in the blood. Insulin resistance is found in 30-70% of patients with PCOS who are overweight or obese, and in patients with normal body weight it occurs in 20-25% of cases. The above facts, as well as our own observations, prompted us to analyze the studied women of fertile age with impaired reproductive system against the background of overweight and obesity. Considering the above, the aim of this study was to identify the relationship between insulin resistance and reproductive disorders in women with overweight and obesity. Material and research methods. The study included 123 women with clinical development of HA and impaired reproductive function, who consulted the consultative clinic of the RSSPMC of Obstetrics and Gynecology of the Ministry of Health of the Republic of Uzbekistan. The criteria for inclusion in the main group were: age of women from 18 to 35 years (average age was 25.8 .. 3.28 years), absence of pregnancy, body mass index over 25 kg / m2. Exclusion criteria from the main group: type 1 and 2 diabetes, pituitary tumors, hypogonadotropichypogonadism, congenital adrenal hyperplasia, hypothyroidism, severe somatic pathology. All patients who applied for the consultation underwent: (1) Collection of anamnestic information. (2) Measurement of anthropometric indicators (height, weight, waist and hip circumference) and assessment of body hair growth using the Ferriman-Hallway scale. (3) Body mass index was
