The impact of poor nutritional health on maternal and infant morbidity and mortality remains high in low- and middle-income countries (LMICs), exacerbated by climate change-linked disasters. Maternal nutritional health, as a modifiable factor, is influenced by various social, political, economic and environmental factors, as well as cultural practices. Identifying climate change-related interventions, adaptive strategies and best practices targeting maternal nutritional health and well-being in LMICs within a cultural context helps inform the co-production of sustainable, culturally sensitive interventions to improve health outcomes for mothers and babies.

We will undertake a systematic review of the literature employing the six steps of the Protocol, Search, Appraisal, Synthesis, Analysis and Report (PSALSAR) framework, including both peer-reviewed and grey literature. The Population, Concept and Context approach will be used to formulate the review question and the inclusion and exclusion criteria. We will include primary research comprising all study designs published in English from 2007 onwards. We will conduct searches in online academic databases, including CINAHL, MEDLINE, Global Health (CABI), AGRIS (FAO) and SCOPUS, as well as defined grey literature sources (ie, Google Scholar). Titles, abstracts and later full-text articles will be independently accessed and screened for eligibility criteria by four researchers. Following the integrative review methodology, we will present findings narratively, organised around the components of the PSALSAR framework to provide a comprehensive synthesis of the available evidence.

As no primary data will be collected, the systematic review does not require formal ethics approval. However, we will give attention to ethical considerations within the identified studies. Findings will be published in a peer-reviewed journal and presented at relevant conferences. The findings of our systematic review and the ethnographic component of our research project will inform the development of appropriate maternal nutritional health interventions using co-production methodology in Pakistan.

To explore dietary intake, diet-related challenges in glucose management and perceived needs for dietary support among Swedish adults with type 1 diabetes (T1D).

Cross-sectional observational study based on an electronic survey that included the validated Meal-Q food frequency questionnaire and additional questions on dietary habits and management. Participant characteristics were retrieved from the Swedish National Diabetes Register. Descriptive and correlation analyses were conducted.

Three diabetes specialist clinics in Sweden.

375 adults with T1D.

Dietary intake and diet-related challenges in glucose management.

A total of 191 persons (mean age 48 years; 48% female) consented to participate. The mean (SD) glycated haemoglobin A1c was 56 (13) mmol/mol, mean glucose 8.8 (2.2) mmol/L, time in range (TIR) 64% (18%) and BMI 27 (4.3) kg/m²; 41% used insulin pumps. Mean carbohydrate intake was 183 g/day (41% of energy, E%). Fibre intake was 23 g/day (3.1 g/MJ), and saturated fat intake was 29 g/day (15 E%), both inconsistent with dietary recommendations. About half (51%) found carbohydrate counting challenging, with 53% estimating carbohydrate intake visually and only 18% using advanced methods. Additionally, 48% reported reducing carbohydrate intake, and 61% avoided certain carbohydrate-rich foods due to glucose management difficulties. Approximately 40% of participants reported insufficient dietary guidance from their healthcare providers since diagnosis, 33% expressed interest in further dietitian support and 39% believed dietary changes could improve glucose control.

Participants reported lower fibre intake and higher saturated fat intake compared with dietary guidelines. Many found carbohydrate counting and carbohydrate-rich meals challenging. One-third expressed a wish for additional dietary support. These findings highlight the importance of improving access to tailored dietary counselling in routine T1D care.
