“…This study revealed that the longer the duration of underhydration, the lower the birth weight of infants. 16 The second RCT study instructed individuals in their third trimester of pregnancy to drink 2 liters of water within 2 hours and an additional 2 liters per day for seven days. The intervention group had a higher rate of normal vaginal deliveries (71.0%) compared to the control group Prior to 16 weeks of pregnancy, (baseline interview) and between 20 and 24 weeks of pregnancy (interview period), telephone interviews were used to gather information on exposures (including water intake) and potential confounding factors (follow-up interview).…”

“…29 A higher proportion of dehydrated urine samples was associated with a lower birth weight when tested in the second trimester. 16 The fi ndings from this study are signifi cant because of the increased demand for water during pregnancy and the widespread failure of pregnant women in many parts of the world to consume enough amounts of water. 9,30,31 Although water consumption appears to be highest in the second trimester and lowest in the third 6,7 , When morning sickness and nausea begin to fade in the second trimester, it removes one potential barrier to exercise.…”

Objective: This systematic review aimed to investigate theeffect of water intake during pregnancy on infant birthweight.Methods: A comprehensive search was conducted usingthe keywords "water intake," "dehydration," "pregnancy,""outcome," "hydration," "birth weight," and "birth outcome"in databases such as "SCOPUS," "EBSCO," "PUBMED,""COCHRANE," and through "Google Search." MeSH headings"pregnancy" and "hydration" were used for the search.Inclusion criteria encompassed pregnant women withoutpathological disorders, birth weight as a studied outcome,prospective cohorts, clinical trial study designs, and Englishlanguagepapers. Out of the 254 articles retrieved, six metthe specifi ed requirements and were included in this review.Results: The fi ndings from the six studies consistentlydemonstrated a positive correlation between higher waterintake, improved hydration, and increased birth weight.All studies measured water consumption or hydrationstatus between 8-37 weeks of gestation. Regardless of theduration of the studies, underhydration or low water intakewas consistently associated with lower birth weight.Conclusion: This review highlights that increasing waterintake among pregnant women positively affects infantbirth weight. Adequate water intake during pregnancy isrecommended to be in the range of 2180 – 3000 mL daily,considering hydration status and the stage of pregnancy.Keywords: birth weight, hydration, pregnancy, water intake.AbstrakTujuan: Untuk mengungkap pengaruh asupan air selamakehamilan terhadap berat lahir bayi.Metode: Menggunakan kata kunci “water intake,""dehydration," "pregnancy," "outcome," "hydration," "birthweight," dan "birth outcome,", artikel dicari.

Dari 254 artikel yang diperoleh, enam artikelmemenuhi persyaratan dan digunakan untuk review ini.Hasil: Dari keenam penelitian menunjukkan bahwa semakintinggi asupan air, semakin baik hidrasi atau asupan airmeningkatkan berat bayi lahir. Semua penelitian mengukurkonsumsi air atau status hidrasi antara 8-37 minggu. Studistudiini secara konsisten memberikan bukti bahwa asupanair yang rendah atau kondisi kekurangan cairan dikaitkandengan berat badan lahir rendah, terlepas dari durasi studi.Kesimpulan: Kajian ini menunjukkan bahwa peningkatanasupan air ibu hamil berpengaruh positif terhadap beratlahir bayi. Asupan air yang cukup pada ibu hamil adalah2180 – 3000 mL setiap hari bergantung pada status hidrasidan usia kehamilan.Kata kunci: asupan air, berat lahir, hidrasi, kehamilan.

“…A third study by Rosinger and colleagues [ 16 ] found evidence to suggest that pregnant women may be at risk for under-hydration in the second and third trimesters when water needs begin to increase. Rosinger and colleagues [ 16 ] examined urine osmolality and under-hydration levels in pregnant women with overweight/obesity participating in the Healthy Mom Zone gestational weight gain regulation intervention [ 17 , 18 ]. As part of a larger, multicomponent intervention, women in the intervention group were encouraged to track their water intake, increase intake of water-dense foods, and meet the hydration guidelines of consuming at least 2.4 L of water from ~8–36 weeks gestation [ 7 , 17 , 18 ].…”

Women used the MyFitnessPal app (a smartphone app used to track daily food and beverage intake, and exercise behaviors; [ 19 ]) to track their daily hydration behaviors and biomarkers of hydration levels (i.e., weekly urine samples) were collected and analyzed to examine hydration levels [ 16 ]. These analyses found that the intervention was successful in promoting proper hydration in pregnant women with overweight/obesity [ 16 ].…”

Maintaining adequate hydration over the course of pregnancy is critical for maternal and fetal health and reducing risks for adverse pregnancy outcomes (e.g., preeclampsia, low placental and amniotic fluid volume). Recent evidence suggests that women may be at risk for under-hydration in the second and third trimesters when water needs begin to increase. Scant research has examined pregnant women’s knowledge of hydration recommendations, water intake behaviors, and willingness to use digital tools to promote water intake. This study aimed to: 1) describe hydration recommendation knowledge and behaviors by the overall sample and early vs late pregnancy, and 2) identify habits and barriers of using digital tools. Pregnant women (N = 137; M age = 30.9 years; M gestational age = 20.9) completed a one-time, 45-minute online survey. Descriptive statistics quantified women’s knowledge of hydration recommendations, behaviors, and attitudes about utilizing digital tools to promote adequate intake, and Mann-Whitney U and chi-squared tests were used to determine group differences. Most women lacked knowledge of and were not meeting hydration recommendations (63%, 67%, respectively) and were not tracking their fluid consumption (59%). Knowledge of hydration recommendations differed by time of pregnancy, such that women in later pregnancy reported 82 ounces compared to women in early pregnancy (49 ounces). Common barriers included: forgetting to drink (47%), not feeling thirsty (47%), and increased urination (33%). Most were willing to use digital tools (69%) and believed a smart water bottle would help them achieve daily fluid recommendations (67%). These initial findings suggest that pregnant women may benefit from useful strategies to increase knowledge, decrease barriers, and maintain adequate hydration, specifically earlier in pregnancy. These findings will inform the design of a behavioral intervention incorporating smart connected water bottles, wearables for gesture detection, and behavior modification strategies to overcome barriers, promote proper hydration and examine its impact on maternal and infant health outcomes.

Water links the environment, culture, and biology. An integrative approach is needed to attain a complete picture of how water affects human biology due to its inherent interdisciplinary nature. First, this review describes advances in human water needs, thirst, and hydration strategies from a biocultural perspective. Second, it provides a critical appraisal of the literatures on water insecurity (WI) experiences and coping strategies used to mitigate WI to illustrate how they intersect to affect human biology through the embodiment framework. Deviations from water needs and heightened WI can alter hydration and coping strategies, which have implications for a suite of psychological and physiological outcomes. These disruptions are embodied in cellular damage, dehydration, nutrition, stress, mental health, cognitive impairment, aging-related effects, cardiometabolic health, and kidney function. Disrupting forces such as lifestyle changes and climate change have important implications for water needs, WI, coping and hydration strategies, and the embodiment of each. Expected final online publication date for the Annual Review of Anthropology, Volume 52 is October 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
