Birth weight, which exhibits variability across different populations, is influenced by a mix of genetic, environmental, and dietary factors originating from both the mother and father. Maternal characteristics, including age, socioeconomic status, prior pregnancies, weight, height, and weight increase throughout pregnancy, have a substantial influence on fetal growth and the health of the infant. On the other hand, the influence of paternal characteristics on the weight of newborns is still not fully comprehended in a consistent manner. Birth weight is an important factor that can help predict various maternal complications, such as the probability of having a C-section, experiencing postpartum hemorrhage or infections. It can also indicate future health challenges like asthma, cognitive impairment, and chronic diseases such as hypertension and diabetes. Nineteen publications were found through a thorough search of the Medline, PubMed, and Scopus databases, which provide insights into how paternal variables contribute to variations in birth weight. Significantly, the age of the father was found to be associated with higher chances of preterm birth and having a smaller size for gestational age in premature infants, while full-term children were more likely to have a larger size for gestational age. In addition, there is a constant correlation between the height of the father and the birth weight of the child. Taller dads are more likely to have babies with a higher birth weight and a lower likelihood of being small for gestational age (SGA). Although there were some discrepancies in the data about the weight and BMI of fathers, it was found that the height of fathers played a significant role in determining the size of the fetus and the weight of the newborn. While there may be differences in the conducted studies, these findings provide valuable insights into the complex connection between parental characteristics and fetal development. This data can be utilized to enhance clinical treatment strategies and enhance our comprehension of outcomes for neonates. Further homogeneous investigations are required to conclusively validate and build upon these findings.

Insulin resistance (IR) plays a pivotal role in the pathogenesis of several dermatological diseases, including psoriasis, acne, acanthosis nigricans, and hidradenitis suppurativa (HS). These conditions are characterized by chronic inflammation, oxidative stress, and metabolic dysfunction, which are exacerbated by IR. This narrative review examines the emerging role of nutraceutical insulin-sensitizing agents (ISAs), including myo-inositol, alpha-lipoic acid, vitamin D, vitamin C, and folic acid, in managing IR-related dermatological disorders. A comprehensive literature search was conducted across Cochrane Library and MEDLINE (1965–May 2025), focusing on clinical trials involving nutraceutical ISAs in dermatological conditions associated with IR. Only human studies published in English were included. Evidence from randomized controlled trials (RCTs) and observational studies suggests that ISAs improve glycemic control, reduce oxidative stress, and modulate inflammatory pathways in IR-related dermatoses. Notably, myo-inositol combined with magnesium and folic acid has demonstrated significant reductions in acne severity, hirsutism, and quality-of-life impairments in women with polycystic ovary syndrome. Similar benefits have been observed in psoriasis and HS, though data remain limited. Nutraceutical ISAs offer a promising adjunctive approach for the management of IR-associated dermatological diseases, potentially addressing both metabolic dysfunction and skin inflammation. However, robust RCTs with long-term follow-up are needed to confirm these preliminary findings and to establish optimal treatment regimens.
