For the assessment of clinical ED, participants were categorised as those who reported being 'sometimes able' or 'never' to maintain an erection based on a single question.

A common, widely accepted, Indian food vehicle for fortification with folate and vitamin B&lt;sub&gt;12&lt;/sub&gt; has long remained elusive. Earlier, we employed folate and vitamin B&lt;sub&gt;12&lt;/sub&gt;-fortified teabags to brew a daily cup of black tea and documented improvement in serum folate and vitamin B&lt;sub&gt;12&lt;/sub&gt; concentrations among women from Maharashtra state within 60 days. Because most Indian households prefer hot-brewed ('loose') black tea prepared by the 'crush, tear, curl' (CTC) method in large commercial tea factories, we tested the feasibility of directly fortifying CTC tea with folate and vitamin B&lt;sub&gt;12&lt;/sub&gt; and assessed its efficacy in improving the folate and vitamin B&lt;sub&gt;12&lt;/sub&gt; status among women from Assam state within 90 days.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Two groups of women studying nursing (n=30) or pharmacy (n=30) at Assam Medical College and Hospital consumed a daily cup of hot tea prepared from 2 g of either unfortified CTC tea (control group) or vitamin-fortified CTC tea containing 1 mg folate and 1 mg vitamin B&lt;sub&gt;12&lt;/sub&gt; (experimental group) for 90 days. We then compared their pre-interventional versus post-interventional changes in serum folate and vitamin B&lt;sub&gt;12&lt;/sub&gt; status, iron status and haemoglobin concentration.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;At baseline, 89% of all women had low folate status (serum folate ≤5 ng/mL) and 72% had low vitamin B&lt;sub&gt;12&lt;/sub&gt; status (serum vitamin B&lt;sub&gt;12&lt;/sub&gt; ≤300 pg/mL). After 90 days daily consumption of unfortified CTC tea, the control group had clinically insignificant mean increases in serum folate of 1.3 ng/mL and serum vitamin B&lt;sub&gt;12&lt;/sub&gt; of 1 pg/mL. By contrast, the experimental group consuming vitamin-fortified CTC tea exhibited a mean rise in serum folate of 5.3 ng/mL (95% CI 3.9 to 6.8; p&lt;0.001) and serum vitamin B&lt;sub&gt;12&lt;/sub&gt; of 194.6 pg/mL (95% CI 154.7 to 234.5; p&lt;0.001). Moreover, 28/30 women receiving vitamin-fortified CTC tea had a post-interventional rise in mean serum folate of 9.2±3.6 (SD) ng/mL, and 25/30 women normalised their serum vitamin B&lt;sub&gt;12&lt;/sub&gt; ≥300 pg/mL.

Maternal IQ and promotion of child autonomy were directly associated with all neurodevelopmental outcomes.</p><p><strong>Conclusion: </strong>Low levels of PAE were not associated with neurodevelopmental impairment at 18 months, except for possible motor impairment at higher exposures: our findings highlight the predominant influence of maternal IQ and the home environment. Further research, including a broader range of alcohol exposure, is needed to better define potential safety thresholds of PAE on early-life neurodevelopment.</p>","PeriodicalId":36307,"journal":{"name":"BMJ Nutrition, Prevention and Health","volume":"8 2","pages":"e001313"},"PeriodicalIF":2.5,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12936528/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147327385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
