Acid Esters

Phthalates (Phthalic acid esters, PAEs) as a common industrial products, a growing body of scientific evidences indicate that exposure to PAEs in early life has a potential harmful effect on the growth and development of organisms in later life, among these hazards, exposure to PAEs widely may increase the risk of asthma in children, which has attracted more and more attention. This article introduced the reasons and effects of PAEs exposure in early life, the relationships between early-life PAEs exposure and childhood asthma from the perspectives of epidemiological and animal studies and the underlying mechanisms of action.

Prior research reveals that negative early-life experiences play a major role in the development of obesity in later life, but few studies identify mechanisms that alter the lifetime risk of obesity. This study examines the influence of negative childhood experiences on body mass index (BMI) and obesity (BMI ≥30) during older adulthood and the psychosocial and behavioral pathways involved. Using a nationally representative sample, we examine the influence of cumulative misfortune as well as five separate domains of misfortune on BMI and obesity. Results show that four of the five domains are associated with BMI and obesity either directly, indirectly, or both. The influence of cumulative misfortune on the outcomes is mediated by three adult factors: socioeconomic status, depressive symptoms, and physical activity. The mediators identified here provide targets for intervention among older adults to help offset the health risks of excess BMI attributable of early-life exposure to misfortune.

Early Life Exposure

ObjectivesThis study aimed to evaluate the association between early-life exposure to the Great Chinese Famine (1959–1961) and the prevalence of poor physical function in midlife.DesignA population-based historical prospective study was performed as part of a wider cross-sectional survey. Exposure to famine was defined by birthdate, and participants were divided into non-exposed group, fetal-exposed group and infant-exposed group.Setting and participantsA total of 3595 subjects were enrolled into the study from the China Health and Retirement Longitudinal Study (CHARLS) 2015 based on random selection of households that had at least one member aged 45 years old and older in 28 provinces of mainland China.Main outcome measuresPhysical function status was assessed by a six-item self-report on the Barthel scale which rated basic activities of daily living (BADL).Results743 (20.7%) out of all participants were exposed to the Great Chinese Famine in their fetal periods, while 1550 (43.1%) participants were exposed at the age of an infant. The prevalence of poor physical function in the non-exposed group, fetal period-exposed group and infant period-exposed group were 12.3%, 15.5% and 17.0%, respectively. Among males, after stratification by gender and severity of famine, the prevalence of poor physical function in the fetal period was significantly higher (OR 2.40, 95% CI 1.18 to 4.89, p=0.015) than the non-exposed group in severely affected areas, even after adjusting for the number of chronic diseases, place of residence, smoking and alcohol drinking habits, marital status, educational level and body mass index. A similar connection between prenatal and early postnatal exposure to the Great Chinese Famine and the prevalence of poor physical function in midlife, however, was not observed from female adults.ConclusionsMales who were exposed to the Great Chinese Famine (1959–1961) present considerably decreased physical function in their later life.

Pass Through

Fluoride, one of the most celebrated ingredients for the prevention of dental caries in the 20th century, has also been controversial for its use in dentifrices and other applications. In the current review, we have concentrated primarily on early-life exposure to fluoride and how it may affect the various organs. The most recent controversial aspects of fluoride are related to toxicity of the developing brain and how it may possibly result in the decrease of intelligence quotient (IQ), autism, and calcification of the pineal gland. In addition, it has been reported to have possible effects on bone and thyroid glands. If nutritional stress is applied during a critical period of growth and development, the organ(s) and/or body will never recover once they pass through the critical period. For example, if animals are force-fed during experiments, they will simply get fat but never reach the normal size. Although early-life fluoride exposure causing fluorosis is well reported in the literature, the dental profession considers it primarily as an esthetic rather than a serious systemic problem. In the current review, we wanted to raise the possibility of future disease as a result of early-life exposure to fluoride. It is not currently known how fluoride will become a cause of future disease. Studies of other nutritional factors have shown that the effects of early nutritional stress are a cause of disease in later life.

The Impact

The aim of the present systematic review was to evaluate the influence of early life exposure (maternal and childhood) to peanuts and the subsequent development of sensitisation or allergy to peanuts during childhood. Studies were identified using electronic databases and bibliography searches. Studies that assessed the impact of non-avoidance compared with avoidance or reduced quantities of peanuts or peanut products on either sensitisation or allergy to peanuts, or both outcomes, were eligible. Six human studies were identified: two randomised controlled trials, two case–control studies and two cross-sectional studies. In addition, published animal and mechanistic studies, relevant to the question of whether early life exposure to peanuts affects the subsequent development of peanut sensitisation, were reviewed narratively. Overall, the evidence reviewed was heterogeneous, and was limited in quality, for example, through lack of adjustment for potentially confounding factors. The nature of the evidence has therefore hindered the development of definitive conclusions. The systematic review of human studies and narrative expert-led reviews of animal studies do not provide clear evidence to suggest that either maternal exposure, or early or delayed introduction of peanuts in the diets of children, has an impact upon subsequent development of sensitisation or allergy to peanuts. Results from some animal studies (and limited evidence from human subjects) suggest that the dose of peanuts is an important mediator of peanut sensitisation and tolerance; low doses tend to lead to sensitisation and higher doses tend to lead to tolerance.

Increased Risk

It is now accepted that the way our health evolves with aging is intimately linked to the quality of our early life. The present review highlights the emerging data of Developmental Origins of Health and Disease field on developmental disruption by toxicants and their subsequent effect on type 2 diabetes. We report adverse neonatal effects of several food contaminants during pregnancy and lactation, among them bisphenol A, chlorpyrifos, perfluorinated chemicals on pancreas integrity and functionality in later life. The described alterations, in conjunction with disruption of β cell mass in early life, can lead to dysregulation of glucose metabolism, insulin synthesis, which facilitates the development of insulin resistance and progression of diabetes in the adult. Despite limited and often inconclusive epidemiologic and experimental data, more recent data clearly show that infants appear to be at increased risk of type 2 diabetes in later life. This may be a result of continued exposure to chemical food contaminants during the critical window of pancreas development. In societies already burdened with increased incidence of non-communicable chronic diseases, there is a clear need for information regarding the potential harmful effects of chemical food contaminants on adult health diseases.
