India continues to be a melting pot of different cultures. Populations having diverse genetic configurations have brought attention to the subcontinent's genetic past. The key question remains, however, whether they share a common genetic ancestry or differ with respect to geography, ethnicity, and language. To understand the genetic relationship among these populations, we performed an intensive review of previously published literature with 3317 individuals from 28 indigenous tribes across India. Results: The studied population exhibited a high degree (0.751-0.909) of heterozygosity at the loci D8S1179, D21S11, and FGA. Most of the NorthEast Indian populations show the least heterozygosity value <0.550 at the locus TH01 which is suggesting small genetic variability. The heterozygosity ranges from 0.719 ± 0.024 (Adi Minyong of Arunachal Pradesh) to 0.845 ± 0.013 (Katkari of Maharastra), and the overall mean is 0.723. Adi Pasi and Adi Komkar of Arunachal Pradesh and Bhils of Gujarat show a relatively moderate level of <75% heterozygosity. The genomic diversity H S and the locus-wise average coefficient of gene diversity G ST range from (76.2%-79.2%) and (0.6%-1.4%). Conclusion: Autosomal STR markers revealed that endogamous tribal populations from the same geographical region exhibited genetic proximity. Depending on these findings, the study explains that genetic distance correlated to their shared geography and ethnicity. The genomic diversity and the locus-wise average coefficient of gene diversity indicate the genetic affinity among tribal populations by ethnicity, language, and geography.

India has witnessed an about 30% rise in PCOS cases in the last couple of years. PCOS has a strong association with many comorbidities with its long-term metabolic as well as other consequences. Thus, it has recently been recognized as a significant public health issue. This review paper is an attempt to reveal the prevalence, pathophysiology, knowledge and awareness of PCOS among the adolescents and young adult women of India. An extensive search was performed using electronic search engines such as PubMed, Scopus, and Google Scholar (from 2004 to 2023) to find the relevant research papers on the prevalence, pathophysiology, knowledge, and awareness of PCOS among the adolescents and young adult women of India. The current review summarises and highlights the prevalence, pathophysiology, knowledge, and awareness of PCOS for early identification and prevention and consequent minimation of the steady upward trend of PCOS. The results of this review could identify high-risk populations and foster the implementation of preventive lifestyle measures. It also investigates the need for intervention programmes for PCOS and its associated comorbidities in different settings at an earlier stage and to improve the quality of health.

The study further attempts to study the perception and practice regarding contraception use and their decision-making ability. The present study was conducted in Kolkata, West Bengal. A total of 64 women (Bengali-speaking Hindus: 34 and Hindi-speaking Hindus: 30) ranging between 15 years and 44 years were chosen by convenience sampling method. Semi-structured interview schedule was employed to record the response of the participants. Sociodemographic profile of the participants and of their husbands and fertility history were collected using structured interview. Open-ended questions were asked to the participants to understand their perception about family planning. Case studies were also taken from each participant to know about their decision-making process of family planning. Descriptive statistic was car...

and the past history of the tribal populations of India
requires the untangling of the confounding influences of
language, ethnicity, and geography on the extant diverse
tribes. The present study examines the genetic relationship
of linguistically (Dravidian, Austro-Asiatic, and
Tibeto-Burman) and ethnically (Australian and East
Asian) diverse tribal populations (46) inhabiting different
regions of the Indian subcontinent. For the purpose,
we have utilized the published data on allele frequency
of 15 autosomal STR loci of our study on six Adi subtribes
of Arunachal Pradesh and compared the same
with the reported allele frequency data, for nine common
autosomal STR loci, of 40 other tribes. Phylogenetic and
principal component analyses exhibit geography based clustering of Tibeto-Burman speakers and separation of
the Mundari and Mon-Khmer speaking Austro-Asiatic
populations. The combined analyses of all 46 populations
show clustering of the groups belonging to same ethnicity
and inhabiting contiguous geographic regions, irrespective
of their different languages. These results help
us to reconstruct and understand three plausible scenarios
of the antiquity of Indian tribal populations: the
Dravidian and Austro-Asiatic (Mundari) tribes
were possibly derived from common early settlers; the
Tibeto-Burman tribes possibly belonged to a different
ancestry and the Mon-Khmer speaking Austro-Asiatic
populations share a common ancestry with some of the
Tibeto-Burman speakers. Am J Phys Anthropol
