Associations of maternal dietary patterns during pregnancy with neonatal obesity among Han and Tibetan maternal-child pairs: results from a prospective birth cohort in Tibetan area.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNeonatal obesity has profound effects across the entire life. Although maternal diet and environmental exposures such as high altitude are potential influencing factors, the modulating effects of the unique high-altitude environment and distinct ethnic dietary patterns prevalent on the Tibetan Plateau remain unexplored. To investigate this association, we utilized Compositional Data Analysis (CoDA) to model dietary patterns.
aimThis study aims to investigate the associations between maternal dietary patterns during pregnancy and neonatal obesity, examining the potential modification effect by altitude and ethnicity. Furthermore, we apply the CoDA approach to quantify the impact of dietary redistribution on obesity risk. The findings are expected to inform targeted dietary interventions and public health strategies for high-risk populations.
methodA birth cohort study encompassed 1173 pregnant women from the Tibetan Plateau. Dietary intake frequency during pregnancy was assessed using the food frequency questionnaire. Principal component analysis was used to identify the dietary patterns. Linear and logistic regression was used to examine the associations between dietary patterns and neonatal obesity. CoDA was employed to assess the association between redistribution of diet servings during pregnancy and altered risk of high ponderal index (HPI).
resultsOf the total 1173 mother-neonate pairs, 40.3% were Tibetans, 22.7% resided in ultra-high altitude areas, and 4.9% of neonates had obesity. Four dietary patterns were identified. A higher protein-fruit pattern score was significantly associated with a lower risk of HPI (OR = 0.66, 95% CI 0.47-0.93). We also observed a modification effect by altitude (P
conclusionHigher adherence to protein-fruit dietary patterns during pregnancy was negatively associated with neonatal obesity in the Tibetans living in ultra-high altitude areas. Encouraging healthy diets during pregnancy, particularly through initiatives such as increasing fruit intake, may help to prevent neonatal obesity.
