    Abstract Objective: The sex ratio at birth, defined as males/total (M/T) approximates 0.515 but is affected by many factors. Acute and chronic stress have been shown to lower M/T, and both regional and racial differences exist. This study analysed regional differences in M/T in Mexico.
    Material and methods: Live births by sex and year were available for 1994-2020. Regional births were available for 2010-2020 for five regions: North, Centre, West, East and South.
    Results: There were 68,423,415 births for 1994-2020 and 25,436,687 for 2010-2020 (M/T=0.5060, 95% confidence interval: 0.5058-0.5062). M/T was <0.515 (p<0.0001). Live births correlated negatively with year (p<0.0001). M/T fell for 1994-2003 then rose to 2020 (p<0.0001). M/T was highest in North followed by West, South, Centre and East (p<0.0001).
    Conclusion: Chronic stress with socioeconomic deprivation may reduce M/T and may explain the low M/T found in this study from Mexico.

  3. Article ; Online: The Sex Ratio at Birth Is Higher in Māori than in Non-Māori Populations in Aotearoa New Zealand.

    Grech, Victor

    Acta medica (Hradec Kralove)

    2023  Volume 66, Issue 1, Page(s) 24–27

    Abstract: Aims: The sex ratio at birth approximates 0.515 (male : total, M/T), with 515 boys per 485 girls. Many factors have been shown to influence M/T including acute and chronic stress. Increasing maternal age is associated with a decline in M/T. In Aotearoa ... ...

    Abstract Aims: The sex ratio at birth approximates 0.515 (male : total, M/T), with 515 boys per 485 girls. Many factors have been shown to influence M/T including acute and chronic stress. Increasing maternal age is associated with a decline in M/T. In Aotearoa New Zealand, circa 15% of the population identify as of Māori heritage. This populationis generally considered to be socioeconomically disadvantaged. This study analysed M/T for Māori and non-Māori M/T births in Aotearoa New Zealand and relates these to mean maternal age at delivery.
    Methods: Live births by sex and maternal age at delivery were available from the website of Tatauranga Aotearoa Stats NZ for 1997-2021.
    Results: This study analysed 1,474,905 births (28.4% Māori) Pooled data shows that Māori M/T is significantly higher than non-Māori M/T (chi = 6.8, p = 0.009). Mean maternal age at delivery was less for Māori mothers but this was not statistically significant.
    Conclusions: Several studies have shown that M/T is decreased in socioeconomically deprived populations, and for this reason Māori M/T is expected to be lower and not higher than non-Māori M/T. A lower mean maternal age at delivery might have explained the M/T differences noted in this analysis but this was not a statistically significant difference.

  4. Article: Publish or perish, information overload, and journal impact factors - A conflicting tripod of forces.

    Abstract The academic mantra, to the point of cliché, is "publish or perish." Academia is generally too preoccupied with research and publishing to stand back and consider the driving forces behind the actual processes and systems involved. Indeed, academics are generally unaware of the factors that influence one's ability to publish: The drive to publish itself, readers' information overload, and editors' desire to increase journals' impact factors. This paper will detail these forces, and it behooves potential researchers to keep this veritable tripod of forces in mind since understanding the tripod may facilitate publication chances through the invocation and active implementation of news media theory. Media writers' remuneration is dependent on readers clicking on their articles. The media reel in readers by displaying an intriguing/bold/provocative headline and then keep the readers interested and hooked with initial sentences that not only give information but also tantalize with the promise of more to come. A paper's title and abstract should adhere to these precepts so as to increase the chances of avoiding immediate rejection at editorial or initial reviewer level.

    Abstract The purpose of research is to seek answers and new knowledge. When conducted properly and systematically, research adds to humanity's corpus of knowledge and hence to our general advancement. However, this is only possible if reported research is accurate and transparent. Guidelines for all the major types of studies (STROBE, CONSORT, PRISMA, MOOSE, STARD, and SPIRIT) have been developed and refined over the years, and their inception, development, and application are briefly discussed in this paper. Indeed, there are currently over 250 of these guidelines for various types of medical research, and these are published by the EQUATOR network. This paper will also briefly review progress in acceptance and adoption of these guidelines.
