Daily Early-Life Exposures to Diet Soda and Aspartame Are Associated with Autism in Males: A Case-Control Study.

ABSTRACT: Since its introduction, aspartame-the leading sweetener in U.S. diet sodas (DS)-has been reported to cause neurological problems in some users. In prospective studies, the offspring of mothers who consumed diet sodas/beverages (DSB) daily during pregnancy experienced increased health problems. We hypothesized that gestational/early-life exposure to ≥1 DS/day (DS_early) or equivalent aspartame (ASP_early: ≥177 mg/day) increases autism risk. The case-control Autism Tooth Fairy Study obtained retrospective dietary recalls for DSB and aspartame consumption during pregnancy/breastfeeding from the mothers of 235 offspring with autism spectrum disorder (ASD: cases) and 121 neurotypically developing offspring (controls). The exposure odds ratios (ORs) for DS_early and ASP_early were computed for autism, ASD, and the non-regressive conditions of each. Among males, the DS_early odds were tripled for autism (OR = 3.1; 95% CI: 1.02, 9.7) and non-regressive autism (OR = 3.5; 95% CI: 1.1, 11.1); the ASP_early odds were even higher: OR = 3.4 (95% CI: 1.1, 10.4) and 3.7 (95% CI: 1.2, 11.8), respectively (p < 0.05 for each). The ORs for non-regressive ASD in males were almost tripled but were not statistically significant: DS_early OR = 2.7 (95% CI: 0.9, 8.4); ASP_early OR = 2.9 (95% CI: 0.9, 8.8). No statistically significant associations were found in females. Our findings contribute to the growing literature raising concerns about potential offspring harm from maternal DSB/aspartame intake in pregnancy.

Project description:BackgroundAdenomyosis can confer life-altering symptoms such as pelvic pain. Yet, the epidemiologic study of this uterine condition lags other gynaecologic conditions. This includes the investigation of intrauterine exposures that could disrupt foetal development and contribute to the presence of adenomyosis in adulthood.ObjectiveWe investigated nine early-life factors and the odds of adenomyosis using data from a population-based case-control study of enrollees of an integrated healthcare system in Washington State ages 18-59.MethodsCases (n = 386) had incident, pathology-confirmed adenomyosis diagnosed between 2001 and 2006. Two control groups were employed: hysterectomy controls (n = 233) and randomly selected age-matched enrollees with an intact uterus ('population controls', n = 323). The primary study activity was a structured in-person interview; participants were also mailed a family history questionnaire that included questions on early-life factors. We conducted logistic regression to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the associations between early-life factors and adenomyosis.ResultsComparing cases to population controls, our data suggested an 80% increased odds of adenomyosis with younger maternal age at participant's birth (≤ 19 vs. ages 25-29) (aOR 1.81, 95% CI 0.94, 3.50) and a 50% increased odds of adenomyosis for participants who were the fourth or later live birth (vs. firstborn) (aOR 1.51, 95% CI 0.88, 2.59). Among never-smoking participants, our data suggested a 50% increased odds of adenomyosis with intrauterine exposure to cigarette smoking (aOR 1.50, 95% CI 0.92, 2.46). In analyses using hysterectomy controls, these associations were attenuated.ConclusionsThese data suggested that several intrauterine exposures were associated with increased odds of adenomyosis in adulthood. The intrauterine period may be a susceptible window for subsequent development of adenomyosis and warrants further investigation.

Project description:BackgroundPhenylketonuria (PKU) is a rare genetic metabolic disorder in which especially high phenylalanine (Phe) concentrations cause brain dysfunction. If untreated, this brain dysfunction results in severe microcephaly, intellectual disability, and behavioral problems. Dietary restriction of Phe is the mainstay of PKU treatment, with long-term successful outcomes. Aspartame, an artificial sweetener sometimes added into medications, is metabolized in the gut into Phe. Then, patients suffering from PKU on a Phe-restricted diet should avoid consumption of aspartame. The aim of our study was to evaluate the number of drugs containing aspartame and/or Phe as an excipient, and to quantify their corresponding Phe intake.MethodsThe list of drugs marketed in France containing aspartame and/or Phe was established using a national medication database called "Theriaque". For each drug, the corresponding daily Phe intake was calculated according to age and weight and was distributed into 3 categories: high (> 40 mg/d), medium (10 to 40 mg/d) and low (< 10 mg/d) Phe intake.ResultsThe number of drugs containing Phe or its precursor aspartame remained very limited (n = 401). Among the aspartame containing drugs, Phe intakes were significant (medium or high) for only half of them whereas there were negligible for the others. Furthermore, these medications with a significant Phe intake were limited to few pharmaceutical classes (mainly antiinfectives agents, analgesics, and drugs for nervous system), and within these classes the drugs were limited to a small number of molecules, including principally amoxicillin, amoxicillin + clavulanic acid and paracetamol/ acetaminophen.DiscussionIn situations requiring the use of these molecules, we propose as an alternative, the use of an aspartame-free form of these molecules or a form with a low Phe intake. If it is not possible, we propose as second-line the use of another antibiotics or analgesics. Finally, we have to remember the benefits-risk balance to use medications containing significant Phe intake in PKU patients. Indeed, it may be better to use a Phe containing medication in the absence of an aspartame-free form of this drug rather than to leave a person with PKU without treatment.
