A scoping review and critical evaluation of the methodological quality of clinical practice guidelines on nutrition in the preconception.

Introduction: Clinical practice guidelines (CPGs) contain recommendations for specific clinical circumstances, including maternal malnutrition. This study aimed to identify the CPGs that provide recommendations for preventing, diagnosing, and treating women's malnutrition. Additionally, we sought to assess the methodological quality using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument.

Development and validation of a new set of indicators to assess the quality of maternal and child nutritional care at the primary care.

Introduction: Maternal and child malnutrition is a worldwide public health problem with short, medium, and long-term adverse consequences for both mother and child. In Mexico, maternal and child malnutrition represents a serious public health problem that must be urgently addressed. In this context, Primary Health Care (PHC) plays an important role in the prevention, detection, monitoring, and treatment of the different forms of maternal and child malnutrition.

Quality Appraisal of Nutritional Guidelines to Prevent, Diagnose, and Treat Malnutrition in All Its Forms during Pregnancy.

This work aimed to identify clinical practice guidelines (CPGs) that include recommendations for the prevention, diagnosis, and treatment of women’s malnutrition during pregnancy and to evaluate the quality of these guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. We conducted a literature review using PubMed and different websites from January 2009 to February 2021. The quality of the CPGs was independently assessed by reviewers using the AGREE II instrument, which defines guidelines scoring >70% in the overall assessment as “high quality”.

Weight gain trajectories patterns from pregnancy to early postpartum: identifying women at risk and timing to prevent weight regain.

Background: Woman's weight changes during pregnancy and postpartum contribute to obesity and health outcomes later in life. This study aimed to identify and characterize weight change trajectories from pregnancy to one year postpartum among adult women.

Methods: We used data from an ongoing cohort of healthy adult women (n = 819) with singleton pregnancies from 2007 - 2011.

Diet Quality Is Associated with a High Newborn Size and Reduction in the Risk of Low Birth Weight and Small for Gestational Age in a Group of Mexican Pregnant Women: An Observational Study.

A high-quality diet during pregnancy may have positive effects on fetal growth and nutritional status at birth, and it may modify the risk of developing chronic diseases later in life. The aim of this study was to evaluate the association between diet quality and newborn nutritional status in a group of pregnant Mexican women. As part of the ongoing Mexican prospective cohort study, OBESO, we studied 226 healthy pregnant women.

Vitamin D Status and Its Determinants in Mexican Pregnant Women from a Rural and an Urban Area: A Comparative Study.

Background: During pregnancy, vitamin D requirements are higher due to fetal growth and development. Vitamin D production occurs mainly through sunlight exposure, which is affected by geographic location and lifestyle factors.

Methods: This was a case-control study nested within two cohorts of adult pregnant women ( = 298): urban (Mexico City) and rural (Cuetzalan).

Quality or Quantity of Proteins in the Diet for CKD Patients: Does "Junk Food" Make a Difference? Lessons from a High-Risk Pregnancy.

How to manage patients with severe kidney disease in pregnancy is still a matter of discussion, and deciding if and when to start dialysis is based on the specialist's experience and dialysis availability. The effect of toxic substances usually cleared by the kidney may be more severe and readily evident. The review, and related case, underlines the importance of considering the presence of additives in food in delicate conditions, such as CKD pregnancy.

Complementary feeding practices and their association with adiposity indicators at 12 months of age.

Nutrition during the first 1000 days of life represents a window of opportunity to reduce the risk of metabolic dysfunctions later in life. Exclusive breastfeeding (EBF) and adequate introduction of solid foods are essential to promote metabolic and nutritional benefits. We evaluated the association of infant feeding practices from birth to 6 months (M) with adiposity indicators at 12 M.

Validity assessment of self-reported weight and its correction process among Mexican adult women of reproductive age.

Objective: We aimed to evaluate the agreement between self-reported weight (SRW) and measured weight (MW) in adult women of reproductive age, identify characteristics associated with the difference between SRW and MW (DW), and develop a correction procedure for SRW.

Methods: We used data from 3,452 non-pregnant or non-lactating adult women who participated in the Mexican Family Life Survey. Standardized personnel asked women about their weight before measuring weight and height.

Higher fat mass and fat mass accretion during the first six months of life in exclusively breastfed infants.

Background: Early nutrition influences infant growth and body composition, which may play a role in the infant's metabolic programming. Breastfed infants appear to have higher fat mass than formula-fed infants, but most comparisons have been cross-sectional, and evidence is scarce. The aim of this study was to describe fat mass and fat mass accretion during the first six months of life and evaluate differences by type of feeding (OMS).

Anthropometric and clinical correlates of fat mass in healthy term infants at 6 months of age.

Background: Body composition in infancy plays a central role in the programming of metabolic diseases. Fat mass (FM) is determined by personal and environmental factors. Anthropometric measurements allow for estimations of FM in many age groups; however, correlations of these measurements with FM in early stages of life are scarcely reported.

Metabolic markers during pregnancy and their association with maternal and newborn weight status.

Background/aims: Obesity during pregnancy increases the risk of adverse clinical outcomes and is associated with low-grade chronic inflammation. We describe maternal metabolic risk and inflammation by maternal weight status, and evaluate the association of metabolic and inflammatory markers with birthweight in a group of pregnant Mexican women.

Methods: This study derived from a prospective cohort of healthy pregnant women <14 weeks of gestation, receiving prenatal care at National Institute of Perinatology (Mexico, 2009-2013).

[Consensus of diagnosis and treatment of obesity in women in reproductive age and climacterium].

Background: The development of obesity is complex and multifactorial, with genetic, biological, environmental and lifestyle of each individual etiology. The different changes in metabolism of women, amongst other factors, lead to disorganization in the distribution of lipids, which gathered in large quantities within the viscera, increases cardiovascular mortality and it is a major determinant factor of the metabolic syndrome.

Objective: To homologate and to apply concepts of evidence-based clinical practice in diagnosis and treatment of obesity in women in reproductive age and climacterium.

Dietary changes associated with improvement of metabolic syndrome components in postmenopausal women receiving two different nutrition interventions.

Objective: This study aims to examine the association between dietary changes and improvement of metabolic syndrome components in Mexican postmenopausal women receiving two different nutrition interventions.

Methods: Women (n = 118) with metabolic syndrome were randomly assigned to group 1 (n = 63; structured hypocaloric diet) or group 2 (n = 55; behavioral therapy). Metabolic and nutrition assessment was performed at baseline and after 2, 4, and 6 months of intervention.

Structured hypocaloric diet is more effective than behavioral therapy in reducing metabolic syndrome in Mexican postmenopausal women: a randomized controlled trial.

Objective: This study aims to compare the effects of a lifestyle intervention using a behavioral therapy (BT) approach with the effects of a cardioprotective structured hypocaloric diet on metabolic syndrome in Mexican postmenopausal women.

Methods: This study is a randomized clinical trial (2006-2009) of Mexican postmenopausal women with metabolic syndrome (Adult Treatment Panel III criteria) who were recruited from the Postmenopause Clinic of the National Institute of Perinatology in Mexico City. Women were assigned to one of two groups--group 1 (structured hypocaloric diet; n = 63): energy restriction (-300 to -500 kcal/d) emphasizing cardioprotective dietary changes; and group 2 (BT; n = 55): goal setting, problem-solving, and stimulus control to achieve cardioprotective dietary and lifestyle recommendations.

[Adherence to a medical nutrition therapy program in pregnant women with diabetes, measured by three methods, and its association with glycemic control].

Introduction: The measurement of adherence to nutrition therapy is essential to evaluate if the outcomes are related to given recommendations.

Material And Methods: The aim of this study was to describe adherence to a Medical Nutrition Therapy Program in Mexican pregnant women with diabetes, using three different methods; and evaluate its association with glycemic control. Adherence was measured with a questionnaire (0-100%), women's self-perception (0-100%) and energy intake adequacy by multiple pass 24 hour recall (85-115% of recommendation).

Correlates of dietary energy sources with cardiovascular disease risk markers in Mexican school-age children.

Dietary and lifestyle changes in Mexico have been linked to an increase in chronic diseases such as obesity and cardiovascular disease. Important dietary changes such as an increase in the consumption of energy-dense foods (high in oils, animal or processed fats, and sugars) have been recently reported. The objective of this study was to identify how key dietary energy sources correlated with other indexes of cardiovascular disease in a Mexican school-age population.
