The Mental Health Outcomes of Food Insecurity and Insufficiency in West Africa: A Systematic Narrative Review. Behav Sci (Basel) 2021; 11:bs11110146. [PMID: 34821607 PMCID: PMC8614760 DOI: 10.3390/bs11110146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2021] [Revised: 10/17/2021] [Accepted: 10/19/2021] [Indexed: 11/29/2022] Open
Abstract
(1) Background: Food insufficiency is a global pandemic affecting many people, especially those residing in developing countries. African countries have been affected by food insufficiency, which is mostly caused by drought or wars. Famine or food insufficiency has been reported to have an impact on the psychological health and quality of life of people affected. This review assessed the mental health outcomes of famine and food insufficiency in West Africa. (2) Methods: A search of the published literature was conducted using PubMed, PsycExtra, Medline, and PsycINFO databases. The search was limited to papers published in English between the years 2010 and 2020. Two reviewers independently screened the titles and abstracts of the retrieved papers using pre-defined inclusion and exclusion criteria and a third reviewer resolved conflicts. Data were extracted and appraised using a data extraction form and an appraisal checklist. (3) Results: A total of 81 papers were identified through the journal databases search. Out of the seven papers that met the inclusion criteria, six papers used cross-sectional designs and one paper used an experimental design. The six papers used quantitative approach for data collection, while the one paper used a qualitative technique. The evidence synthesized from this review indicated that exposure to food insecurity or insufficiency is associated with increased psychological distress including anxiety, sleeplessness, intellectual disability, general mental, and emotional instability. (4) Conclusions: This review strongly highlights the need for further research across the sub-region. It further suggests that famine and food insufficiency are associated with significant mental health problems in adults and impacts the cognitive and intellectual development of children. Although there is paucity of literature about famine and its impact on mental health in West Africa, these findings are important for developing social policy initiatives for increasing food supply and mental health interventions for all ages.

HEALTH ECONOMICS 2021; 30:1600-1627. [PMID: 33880821 DOI: 10.1002/hec.4274] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 02/27/2021] [Accepted: 03/29/2021] [Indexed: 06/12/2023]
Abstract
We investigate the long-term effects of the 1944-45 Great Vietnam Famine on early-life survivors and their offspring using census data, household survey data and historical administrative data. Unlike previous famine studies, we measure famine severity using a unique, more direct, and "plausibly exogenous" metric of food availability: province-level excess paddy (rice) production per capita in 1944. Our study makes two novel contributions. First, we overcome several selection problems associated with the estimation of true famine effects, given the short duration and spatial variation of the Vietnamese famine. Second, we investigate the intergenerational effects of famine, focusing specifically on the occupation of the survivors' parents and the school participation of the survivors' offspring. Our preferred specification estimates generalized triple differences that allow us to control for birth-year and birth-province fixed effects and nation-wide shocks. Our findings suggest that the Vietnamese famine reduced literacy by around 3 percent, BMI by 5.6%-8.4%, arm-length by 4.5%-6.7% (1.1-1.7 cm), height by 2.2%-3.2% (3.4-5 cm), and weight by 10%-14% (4.7-6.9 kg) among the affected cohort. These detrimental famine effects also extended to economic welfare, in the form of lower household incomes and lower non-food household expenditures in adulthood. We also document a 4.9%-7.2% reduction in school participation among survivors' offspring, which has major implications for the exogenous origins of social mobility, inequality, and poverty.

Abstract
Objective To evaluate the effect of undernutrition when young on the risk of poor renal
function in adulthood in women with diabetes mellitus. Methods We studied diabetic women born between 1921 and 1958 who were exposed to the
1959-to-1962 Chinese famine when they were 0 to 37 years old. Exposure age
was classified as young adulthood (18 to 37 years), adolescence (10 to 17
years), or childhood (0 to 9 years). The Adolescence group, which was
provided with the largest amount of food during the famine, was used as the
control group, and variance and binary logistic regression analyses were
performed. Results The prevalences of low estimated glomerular filtration rate (eGFR) in the
Childhood, Adolescence, and Young adulthood groups were 5.26%, 22.39%, and
79.24%, respectively. The risk of low eGFR for the Young adulthood group
(odds ratio [OR] 1.65, 95% confidence interval [CI] 1.10, 2.48), but not for
the Childhood group (OR 1.10, 95% CI 0.68, 1.78), was higher than that for
the Adolescence group after adjustment for potential confounders. Conclusions Undernutrition during young adulthood significantly increases the risk of
renal dysfunction in adult women with diabetes. Therefore, the nutrition of
less affluent young women should be improved.

Abstract
The relationship between famine and migration has not been studied adequately to date. A systematic review of scholarship centred on famine and its demographic, political, and socioeconomic effects demonstrates the paucity of academic attention to the issue. This paper surveys the dominant hypotheses and findings regarding the connection between famine and migration. It delineates key questions that an interdisciplinary and case-based exploration of the subject should address, highlighting gaps in the literature with respect to population-level analyses. Primary observations about the literature reviewed include tenuous generalisations about the linkage between famine and migration and partial examination of the role of politics in enabling or prohibiting mobility during hunger-related crises. In addition, disciplinary silos influence which particular aspects of a famine are scrutinised and which are not appraised. In view of these concerns, international legal and humanitarian norms governing migration also need to pay closer attention to its association with famine.

Abstract
Increasing studies have demonstrated that gene and famine may interact on type 2 diabetes risk. The data derived from the cross-sectional 2010-2012 China National Nutrition and Health Survey (CNNHS) was examined to explore whether gene and famine interacted to influence type 2 diabetes risk. In total, 2216 subjects were involved. The subjects born in 1960 and 1961 were selected as the famine-exposed group, whereas subjects born in 1963 were selected as the unexposed group. A Mass Array system was used to detect the genotypes of 50 related single-nucleotide polymorphisms (SNPs). Interactions were found between prenatal exposure to famine and ten SNPs (rs10401969, rs10886471, rs10946398, rs1470579, rs2796441, rs340874, rs3794991, rs5015480, rs7961581, and rs9470794) on type 2 diabetes risk after adjustments. The stratified results showed that famine exposure exacerbated the effect of CILP2-rs10401969 to fasting serum insulin (FINS), GRK5-rs10886471 to fasting plasma glucose (FPG) and FINS, IGF2BP2-rs1470579 to FINS, TLE1-rs2796441 to impaired fasting glucose (IFG), PROX1-rs340874 to impaired glucose tolerance (IGT), GATAD2A-rs3794991 to FINS, TSPAN8/LGR5-rs7961581 to FPG, and ZFAND3-rs9470794 to IGT and FINS. Famine exposure weakened the effect of CDKAL1-rs10946398 to type 2 diabetes. Famine exposure weakened the effect of HHEX-rs5015480 to IFG, but exacerbated the effect of HHEX-rs5015480 to FINS. The present study suggests that ten SNPs may affect type 2 diabetes risk in interaction with prenatal exposure to Chinese famine.

Abstract
CONTEXT The double burden of malnutrition (DBM), undernutrition in early life and an obesogenic environment later on, influences later risk of chronic disorders. The Great Famine in China from 1959 to1962 and remarkable economic development from the 1980s provided such a burden for a large number of people in their 60s. OBJECTIVE We aimed to analyze the effect of economic status on the association between famine exposure in early life and hyperuricemia in adulthood. DESIGN AND SETTING Participants numbering 12 666 were enrolled in China based on the Survey on Prevalence in East China for Metabolic Diseases and Risk Factors (SPECT-China) Study from 2014 to 2016. PARTICIPANTS Participants with fetal or childhood famine exposure (birth year 1949-1962) formed the exposure group. MAIN OUTCOME MEASURE Hyperuricemia was defined as uric acid (UA) > 420 μmol/L for men and > 360 μmol/L for women. The association of famine with hyperuricemia was assessed via regression analyses. RESULTS Early-life famine exposure was negatively associated with UA levels (P = .045) but was not associated with hyperuricemia (P = .226) in the whole study population. Economic status could moderate the association of famine exposure with UA and hyperuricemia (P ≤ .001). In participants with high economic status, early-life famine exposure was positively associated with UA levels (unstandardized coefficients 7.61, 95% CI 3.63-11.59, P < .001), and with hyperuricemia (odds ratio 1.47, 95% CI 1.19-1.81, P < .001). CONCLUSIONS Economic status could moderate the association between exposure to famine in early life and hyperuricemia in adulthood, indicating that the DBM might affect hyperuricemia in an opposite direction of the effects of undernutrition in early life alone.

Abstract
BACKGROUND Early life exposure to famine and adulthood obesity increased the risk of nonalcoholic fatty liver disease (NAFLD) in adulthood. However, the joint effects on adulthood NAFLD risk are not clear. AIM This study aimed to explore the joint effects of famine exposure and adulthood obesity on NAFLD risk in later life. METHODS We included 7632 subjects aged ≥40 years from a community-dwelling population. Participants were divided into 4 famine exposure groups according to the birth year, including nonexposed (1963-1974), fetal-exposed (1959-1962), childhood-exposed (1949-1958) and adolescent-exposed (1941-1948). General obesity was assessed by body mass index (BMI: overweight ≥24.0 kg/m2 , obesity ≥28.0 kg/m2 ) and abdominal obesity assessed by waist-to-hip ratio (WHR, men/women: moderate ≥0.90/0.85, high ≥0.95/0.90). RESULTS Compared with nonexposed, fetal- and childhood-exposed participants show an increased risk of NAFLD with multivariable-adjusted odds ratio (OR) and 95% confidence interval (CI) of 1.28 (1.02-1.61) and 1.40 (1.04-1.88) respectively. After further adjusting BMI and WHR, the increased risk was observed only in childhood-exposed participants (OR = 1.46, 95% CI = 1.04-2.05). Significant interaction between famine exposure and general obesity on the risk of NAFLD was observed in women (P for interaction = .02). No significant interactions were detected between famine exposure and abdominal obesity (all P for interaction >.05). Compared with normal-BMI and -WHR participants, those with both general and abdominal obesity in adulthood had 20.74 (95% CI: 12.00-35.96), 14.45 (8.76-23.86), 23.02 (16.28-32.57) and 13.04 (8.30-20.48)-fold higher risk in nonexposed, fetal-, childhood- and adolescent-exposed groups respectively. CONCLUSION Coexistence of early life famine exposure and adulthood obesity was associated with a higher risk of NAFLD.

Abstract
Fetal exposure to famine may have long-term consequences in adulthood. The purpose of the present study was to explore the association between famine exposure in fetal life (Chinese famine in 1959–1961) and obesity risk in adulthood. A total of 8054 subjects (3422 male, 4632 female) were recruited from the cross-sectional 2010–2012 China National Nutrition and Health Survey (CNNHS). The subjects born in 1960 and 1961 were selected as the exposed group, while the subjects born in 1963 were selected as the unexposed group. Multiple linear or logistic regression was performed to examine the association between fetal exposure to famine and risk of obesity (body mass index (BMI), waist circumference (WC), obesity, central obesity) adjusting for gender, education level, economic status, physical exercise, sedentary time, smoking, drinking, the intake of livestock and poultry and the intake of cereal and beans. Compared with the unexposed group, WC increased by 0.52 cm after adjusting the covariates (p = 0.021) and females in the exposed group had a significantly higher prevalence of central obesity with an odds ratio (OR) of 1.15 (1.01,1.31) after adjusting the confounders (p = 0.030). WC increased by 0.71 cm, 1.21 cm after adjusting the covariates compared with the unexposed group among the total subjects and the female subjects in urban areas (p = 0.021, p = 0.001). The female subjects had a significantly higher prevalence of obesity and central obesity, with ORs of 1.34 (1.04,1.71) (p = 0.022), 1.28 (1.07,1.53) (p = 0.008) respectively. Our results suggest that fetal exposure to the Chinese famine increased obesity risk in adulthood, and the association was stronger in female and urban subjects.

Abstract
According to Turnbull's 1972 ethnography The Mountain People, the Ik of Uganda had a culture of selfishness that made them uncooperative. His claims contrast with two widely accepted principles in evolutionary biology, that humans cooperate on larger scales than other species and that culture is an important facilitator of such cooperation. We use recently collected data to examine Ik culture and its influence on Ik behaviour. Turnbull's observations of selfishness were not necessarily inaccurate but they occurred during a severe famine. Cooperation re-emerged when people once again had enough resources to share. Accordingly, Ik donations in unframed Dictator Games are on par with average donations in Dictator Games played by people around the world. Furthermore, Ik culture includes traits that encourage sharing with those in need and a belief in supernatural punishment of selfishness. When these traits are used to frame Dictator Games, the average amounts given by Ik players increase. Turnbull's claim that the Ik have a culture of selfishness can be rejected. Cooperative norms are resilient, and the consensus among scholars that humans are remarkably cooperative and that human cooperation is supported by culture can remain intact.

Abstract
OBJECTIVE Many population studies have shown that maternal prenatal nutrition deficiency may increase the risk of neurodevelopmental disorders in their offspring, but its potential transcriptomic effects on brain development are not clear. We aimed to investigate the transcriptional regulatory interactions between genes in particular pathways responding to the prenatal nutritional deficiency and to explore their effects on neurodevelopment and related disorders. RESULTS We identified three modules in rat hippocampus responding to maternal prenatal nutritional deficiency and found 15 key genes (Hmgn1, Ssbp1, LOC684988, Rpl23, Gga1, Rhobtb2, Dhcr24, Atg9a, Dlgap3, Grm5, Scn2b, Furin, Sh3kbp1, Ubqln1, and Unc13a) related to the rat hippocampus developmental dysregulation, of which Hmgn1, Rhobtb2 and Unc13a related to autism, and Dlgap3, Grm5, Furin and Ubqln1 are related to Alzheimer's disease, and schizophrenia. Transcriptional alterations of the hub genes were confirmed except for Atg9a. Additionally, through modeling miRNA-mRNA-transcription factor interactions for the hub genes, we confirmed a transcription factor, Cebpa, is essential to regulate the expression of Rhobtb2. We did not find singificent singals in the prefrontal cortex responding to maternal prenatal nutritional deficiency. CONCLUSION These findings demonstrated that these genes with the three modules in rat hippocampus involved in synaptic development, neuronal projection, cognitive function, and learning function are significantly enriched hippocampal CA1 pyramidal neurons and suggest that three genetic regulatory subnetworks and thirteen key regulating genes in rat hippocampus perturbed by a prenatal nutrition deficiency. These genes and related subnetworks may be prenatally involved in the etiologies of major brain disorders, including Alzheimer's disease, autism, and schizophrenia. METHODS We compared the transcriptomic differences in the hippocampus and prefrontal cortex between 10 rats with prenatal nutritional deficiency and 10 rats with prenatal normal chow feeding by differential analysis and co-expression network analysis. A network-driven integrative analysis with microRNAs and transcription factors was performed to define significant modules and hub genes responding to prenatal nutritional deficiency. Meanwhile, the module preservation test was conducted between the hippocampus and prefrontal cortex. Expression levels of the hub genes were further validated with a quantitative real-time polymerase chain reaction based on additional 40 pairs of rats.

Abstract
A systematic review and meta-analysis of observational studies was performed to provide a deeper understanding of the associations between foetal and childhood exposure to famine and the risks of type 2 diabetes mellitus (T2DM), metabolic syndrome, hypertension, hyperglycaemia, dyslipidaemia, obesity, overweight, coronary heart disease, stroke, and nonalcoholic fatty liver disease (NAFLD) in adulthood. Both foetal and childhood exposure to famine were positively associated with the risks of T2DM (foetal exposure: RR 1.37, 95% CI, 1.23-1.52; childhood exposure: RR 1.33, 95% CI, 1.08-1.64), metabolic syndrome (RR 1.26, 95% CI, 1.07-1.50; RR 1.24, 95% CI, 1.13-1.35), hypertension (RR 1.30, 95% CI, 1.07-1.57; RR 1.33, 95% CI, 1.02-1.74), hyperglycaemia (RR 1.27, 95% CI, 1.11-1.45; RR 1.25, 95% CI, 1.10-1.42), dyslipidaemia (RR 1.48, 95% CI, 1.33-1.66; RR 1.27, 95% CI, 1.12-1.45), obesity (RR 1.19, 95% CI, 1.02-1.39; RR 1.13, 95% CI, 1.00-1.28), overweight (RR 1.17, 95% CI, 1.07-1.29; RR 1.07, 95% CI, 1.00-1.14), coronary heart disease (RR 1.22, 95% CI, 1.00-1.51; RR 1.21, 95% CI, 1.09-1.35), and moderate-to-severe NAFLD (RR 1.66, 95% CI, 1.07-2.57; RR 1.68, 95% CI, 1.41-1.99) in adulthood. No association was observed for the risks of stroke or mild NAFLD. Adjustments for age, alcohol, smoking, body mass index, and physical activity nullified some associations. The associations were generally stronger in women than in men. In summary, foetal and childhood exposure to famine may confer greater risks of developing certain cardiometabolic conditions in adulthood, particularly in women. The extent to which risks for cardiometabolic conditions are associated with early-life famine appears to be determined by certain factors in adulthood.

Abstract
OBJECTIVES We compared δ15 N and δ13 C values from bone and dentine collagen profiles of individuals interred in famine-related and attritional burials to evaluate whether individuals in medieval London who experienced nutritional stress exhibit enriched nitrogen in bone and tooth tissue. Dentine profiles were evaluated to identify patterns that may be indicative of famine during childhood and were compared with the age of enamel hypoplasia (EH) formation to assess whether isotopic patterns of undernutrition coincide with the timing of physiological stress. MATERIALS AND METHODS δ15 N and δ13 C isotope ratios of bone collagen were obtained from individuals (n = 128) interred in attritional and famine burials from a medieval London cemetery (c. 1120-1539). Temporal sequences of δ15 N and δ13 C isotope profiles for incrementally forming dentine collagen were obtained from a subset of these individuals (n = 21). RESULTS Results indicate that individuals from attritional graves exhibit significantly higher δ15 N values but no significant differences were found between burial types for the sexes. Analyses of dentine profiles reveal that a lower proportion of famine burials exhibit stable dentine profiles and that several exhibit a pattern of opposing covariance between δ15 N and δ13 C. EH were also observed to have formed during or after the opposing covariance pattern for some individuals. CONCLUSIONS The results of this study may reflect differences in diet between burial types rather than nutritional stress. Though nutritional stress could not be definitively identified using bone and dentine collagen, the results from dentine analysis support previous observations of biochemical patterns associated with nutritional stress during childhood.

Abstract
Background Previous studies reported that early‐life exposure to undernutrition is associated with the risk of diabetes mellitus and metabolic syndrome in adulthood, but the association with risk of cardiovascular disease (CVD) later in life remains unclear. The current study aimed to investigate whether exposure to Chinese famine in early life is associated with risk of CVD. Methods and Results We used data from REACTION (Risk Evaluation of Cancers in Chinese Diabetic Individuals: A Longitudinal Study), which recruited a total of 259 657 community‐dwelling adults aged 40 years or older from 25 centers across mainland China between 2011 and 2012. Compared with the nonexposed participants, those who had been exposed to famine in early life had a significantly increased risk of total CVD, myocardial infarction, stroke, and coronary heart disease. In the multivariable‐adjusted logistic regression model, the odds ratios (95% CI) for total CVD, myocardial infarction, stroke, and coronary heart disease in fetal famine exposure were 1.35 (1.20–1.52), 1.59 (1.08–2.35), 1.40 (1.11–1.78), and 1.44 (1.26–1.65), respectively; those odds ratios in childhood famine exposure were 1.59 (1.40–1.81), 2.20 (1.52–3.20), 1.82 (1.45–2.28), and 1.80 (1.56–2.09), respectively; and those in adolescent famine exposure were 1.52 (1.27–1.81), 2.07 (1.28–3.35), 1.92 (1.42–2.58), and 1.83 (1.50–2.24), respectively. The main finding of our study is that, compared with those who lived in the less severely affected famine area, individuals in the severely affected famine area had significantly increased risk of total CVD in all 3 exposed groups. Conclusions Early‐life exposure to undernutrition is associated with significantly increased risk of CVD in later life, especially among those who were in the severely affected famine area.

Exposure to Chinese Famine in Fetal Life and the Risk of Dysglycemiain Adulthood. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17072210. [PMID: 32218356 PMCID: PMC7177851 DOI: 10.3390/ijerph17072210] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 03/21/2020] [Accepted: 03/23/2020] [Indexed: 11/16/2022]
Abstract
Undernutrition in early life may have a long consequence of type 2 diabetes in adulthood. The current study was aimed to explore the association between famine exposure in fetal life during China's Great Famine (1959-1961) and dysglycemia in adulthood. The cross-sectional data from 7830 adults from the 2010-2012 China National Nutrition and Health Surveillance was utilized. Participants who were born between 1960 and 1961 were selected as the exposed group, while the participants who were born in 1963 were selected as the unexposed group. Logistic regression was utilized to examine the relationship between fetal famine exposure and dysglycemia in adulthood. The prevalence of type 2 diabetes in the exposed and control group was 6.4% and 5.1%, respectively, and the risk of type 2 diabetes in the exposed group was 1.23 times higher than that of the control group (95%CI, 1.01-1.50; P = 0.042) in adulthood, and 1.40 times in the severely affected area (95%CI, 1.11-1.76; P = 0.004). The fasting plasma glucose of the exposed group was higher than that of the control group, which was only found in the severely affected area (P = 0.014) and females (P = 0.037). The association between famine and impaired fasting glucose was observed only in females (OR 1.31, 95%CI, 1.01-1.70; P = 0.040). Our results suggested that fetal exposure to Chinese famine increased the risk of dysglycemia in adulthood. This association was stronger in the severely affected area and females.

Abstract
BACKGROUND We aimed to assess whether early life exposure to the Chinese famine (1959-1961) modifies the association between type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) in adulthood. METHODS Data from 4247 adults born between 1954 and 1964 from the 2011 and 2015 China Health and Retirement Longitudinal Study (CHARLS) were analyzed. CVD in 2011 and 2015 was based on self-reported doctor's diagnosis of cardiac events (heart attack, coronary heart disease, angina, congestive heart failure, or other heart problems) and stroke. Diabetes in 2011 was defined by fasting blood glucose, HbA1C, or known diabetes. RESULTS Diabetes in 2011 was cross-sectionally associated with an increase of CVD risk in 2011 (OR 1.91, 95%CI 1.53-2.40, P < 0.001) after adjusting for age and gender. Famine exposure changed the association between diabetes and CVD in areas severely affected by famine. The odds ratios (OR) of diabetes in 2011 for CVD in 2015 were 1.24 (95%CI 0.73-2.10), 1.27 (95%CI 0.72-2.24), 2.25 (95%CI 1.29-3.91), 4.31 (95%CI 2.07-8.97) and 1.72 (95%CI 0.84-3.51) among adults in late childhood-, mid-childhood-, early childhood-, fetal-, and nonexposed cohorts in severe famine areas, respectively. CONCLUSION T2DM is associated with the risk of CVD among Chinese adults. Fetal and early childhood exposure to the Chinese famine exacerbated the associated risk.

Abstract
Schizophrenia (SCZ) is a complex, frequently disabling psychiatric disorder. Prenatal exposure to famine, an environmental factor, plays a significant role in the cause of SCZ. We used DNA methylation related sites to analyze their association with prenatal famine exposure and SCZ risk in a Northeast Han Chinese population. A total of 967 subjects (446 patients with SCZ/521 health controls) were recruited. Five single-nucleotide polymorphisms (rs2300149 in ITIH1, rs2675956 in NGEF, rs3758543 in NT5C2, rs7003288 in NA, and rs871925 in MAD1L1) were selected and genotyped. Genotype distribution and allele frequency analysis indicated that rs871925 was significantly associated with SCZ. We also found a significant association between prenatal exposure to famine and rs871925 in the recessive model in the health control group. The generalized multifactor dimensionality reduction analysis suggested a five-locus interaction model association with the risk of developing SCZ. Our data suggested that MAD1L1 rs871925 was associated with prenatal famine exposure and SCZ susceptibility in a Northeast Han Chinese population.

Abstract
This paper describes the findings of studies among men and women who were born around the time of the Dutch famine of 1944-1945, investigating the effects of undernutrition during critical periods of development on later health and disease. The Dutch famine was remarkable in several ways and its unique features have allowed scientists to investigate the long-term consequences of prenatal undernutrition in humans. The effects of undernutrition depended on its timing during gestation, and the organs and tissues undergoing critical periods of development at that time. Early gestation appeared to be the most vulnerable. The effects of famine were widespread and affected the structure and function of many organs and tissues, resulted in altered behaviour and increased risks of chronic degenerative diseases, which in turn led to reduced participation in the labour market and increased mortality. Also, the effects of famine were independent of size at birth, which suggests that programming may occur without altering size at birth. Studies in other settings show that those faced with undernutrition during the critical earliest stages of development have increased rates of chronic generative disease in adult life. This suggests that these findings reflect biologically fundamental processes that describe human plasticity. These findings teach us the fundamental importance of a good start in life. Adequately feeding women before and during pregnancy will allow future generations to reach their full potential and lead healthier and more productive lives, ultimately leading to healthier and more equal future.

Abstract
Alzheimer's disease (AD) is a devastating slowly progressive neurodegenerative disorder with no cure. While there are many hypotheses, the exact mechanism causing this pathology is still unknown. Among many other features, AD is characterized by brain hypometabolism and decreased sugar availability, to which neurons eventually succumb. In light of this aspect of the disease, we hypothesized that boosting fuel supply to neurons may help them survive or at least alleviate some of the symptoms. Here we demonstrate that live moss Physcomitrella patens cells can be safely co-cultured with human fibroblasts in vitro and thus have a potential for providing human cells with energy and other vital biomolecules. These data may form the foundation for the development of novel approaches to metabolic bioengineering and treatment of diseased cells based on live plants. In addition, by providing alternative energy sources to human tissues, the biotechnological potential of this interkingdom setup could also serve as a springboard to foster innovative dietary processes addressing current challenges of mankind such as famine or supporting long-haul space flight.

Abstract
Previous studies on the Chinese famine suggested long-term effects of early-life famine exposure on health conditions. This study aims to investigate the association between exposure to the Chinese famine of 1959-1961 at different early-life stages and the risk of cognitive decline in adulthood. A total of 6417 adults born between 1952 and 1964 in the 2015 survey data of China Health and Retirement Longitudinal Study were included in this study. Cognitive performance was estimated through a series of comprehensive neuropsychological tests, including the Telephone Interview of Cognitive Status (TICS-10), word recall, and pentagon drawing. Multiple generalized linear model (GLM) was employed to detect the association between multi-stage early-life famine exposure and late-life cognitive performance. Compared with the unexposed group, respondents exposed to famine in the fetal period performed worse in the TICS (difference -0.52, 95% confidence interval (CI): -0.93 to -0.10), word recall (difference -0.46, 95% CI: -0.74 to -0.19), and general cognition (difference -1.05, 95% CI: -1.64 to -0.47). Furthermore, we also found negative effects of famine exposure on performance of word recall and pentagon drawing in the early (word recall difference -0.56, 95% CI: -1.00 to -0.11; pentagon drawing difference -0.76, 95% CI: -1.40 to -0.12), mid (word recall difference -0.46, 95% CI: -0.81 to -0.11; pentagon drawing difference -0.66, 95% CI: -1.16 to -0.16), and late (word recall difference -0.30, 95% CI: -0.55 to -0.04; pentagon drawing difference -0.75, 95% CI: -1.13 to -0.37) childhood-exposed groups. Early-life famine exposure in different stages is positively associated with late-life cognitive decline. Fetal famine exposure might affect the overall cognitive status in adulthood, and childhood famine exposure has potential adverse effects on visuospatial episodic memory.

Abstract
Background: Anthropogenic global warming, interacting with social and other environmental determinants, constitutes a profound health risk. This paper reports a comprehensive literature review for 1989⁻2013 (inclusive), the first 25 years in which this topic appeared in scientific journals. It explores the extent to which articles have identified potentially catastrophic, civilization-endangering health risks associated with climate change. Methods: PubMed and Google Scholar were primarily used to identify articles which were then ranked on a three-point scale. Each score reflected the extent to which papers discussed global systemic risk. Citations were also analyzed. Results: Of 2143 analyzed papers 1546 (72%) were scored as one. Their citations (165,133) were 82% of the total. The proportion of annual papers scored as three was initially high, as were their citations but declined to almost zero by 1996, before rising slightly from 2006. Conclusions: The enormous expansion of the literature appropriately reflects increased understanding of the importance of climate change to global health. However, recognition of the most severe, existential, health risks from climate change was generally low. Most papers instead focused on infectious diseases, direct heat effects and other disciplinary-bounded phenomena and consequences, even though scientific advances have long called for more inter-disciplinary collaboration.

Abstract
BACKGROUND Studies have revealed the association between famine in early life and type 2 diabetes mellitus (T2DM) in adulthood. However, studies on the Great Chinese Famine were not conducted nationwide. Because of regional variations in the severity of this famine, the results of regional studies are limited. This study explored associations between famine and T2DM in adulthood in a nationwide study. METHODS The present study was performed on 7262 participants who were born between 1 October 1949 and 1 July 1966 using baseline data collected for the China Health And Retirement Longitudinal Study (CHARLS) in 2011. Participants were divided according to birthdate into cohorts with fetal, late, middle, and early childhood exposure and no exposure to famine. Logistic regression models were used to analyze the association between famine exposure in early life and the risk of T2DM and hyperglycemia in adulthood. RESULTS For females, the risk of hyperglycemia was higher for famine-exposed than not exposed cohort (odds ratios [OR] 1.34 and 95% confidence intervals [CIs]: 1.34 [1.04-1.74], 1.48 [1.15-1.90], 1.38 [1.06-1.79], and 1.57 [1.25-1.98] for fetal, early, middle, and late childhood exposure, respectively), and this association was even stronger in female participants who lived in rural areas before the age of 16 years. In males, the risk of T2DM was lower for the early and late childhood exposure than no exposure cohorts (OR [95% CIs]: 0.65 [0.49-0.86] and 0.74 [0.56-0.98], respectively). [Correction added on 23 July 2018, after first online publication: Parts of the above 'Results' section have been corrected to interchange the citation of the words 'late' and 'early'.] CONCLUSION: Exposure to famine during early life can increase the risk of hyperglycemia in female adults, but may decrease the risk of T2DM in males.

Abstract
Evidence suggests that nutritional status during fetal development and early life leaves an imprint on the genome, which leads to health outcomes not only on a person as an adult but also on his offspring. The purpose of this study is to bring forth an overview of the relevant parameters that need to be collected to assess the long-term and transgenerational health outcomes of famine. A literature search was conducted for the most pertinent articles on the epigenetic effects of famine. The results were compiled, synthesized and discussed with an expert in genetics for critical input and validation. Prenatal and early life exposure to famine was associated with metabolic, cardiovascular, respiratory, reproductive, neuropsychiatric and oncologic diseases. We propose a set of parameters to be collected in disaster settings to assess the long-term outcomes of famine: PALTEM (parameters to assess long-term effects of malnutrition).

Abstract
Background Nutritional deprivation during growth and development may contribute to colorectal cancer (CRC) risk in later life. Methods We studied 7906 women who were aged 0-21 years during the 1944-45 Dutch famine, who enrolled in the Prospect-EPIC study between 1993 and 1997. We used Cox proportional hazard analyses to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for colorectal (proximal, distal and rectal) cancer risk across self-reported famine exposure and exposure-age categories, while adjusting for potential confounders. Results During a median of 17.3 years of follow-up, 245 CRC cases occurred. Moderately and severely famine-exposed women showed a respective 24% and 44% higher CRC risk compared with women who reported no exposure [HR moderate 1.24 (95% CI: 0.93-1.64); HR severe 1.44 (1.03-2.03); P trend 0.027]. This relation attenuated when adjusted for potential confounders [adjusted HR moderate 1.15 (0.87-1.53); HR severe 1.35 (0.96-1.90); P trend 0.091]. Stratified results suggested that severe famine exposure between 10 and 17 years of age was particularly related to CRC risk[adjusted HR moderate 1.39 (0.91-2.11); HR severe 1.76 (1.10-2.83); P trend 0.019; P interaction(famine*10-17yrs) 0.096]. Overall, we found no differences in famine effects across CRC subsites, but age-at-exposure stratified results suggested an increased risk for proximal CRC in those aged 10-17 years during exposure to the famine [adjusted HR moderate 2.14 (1.06-4.32), HR severe 2.96 (1.35-6.46); P trend 0.005]. Overall and within age-at-exposure categories, tests for subsite specific heterogeneity in famine effects were not significant. Conclusions Our findings suggest that severe exposure to a short period of caloric restriction in pre-adult women may relate to CRC risk decades later.

Abstract
Background Existing studies of the 1944-45 Dutch famine found little evidence of the association between early life malnutrition and midlife cognition. Methods Among 2446 rural participants born between 1958 and 1963 in the China Health and Retirement Longitudinal Study, we examined effects of exposure to China's 1959-61 Great Leap Forward famine during prenatal and early postnatal life, on four cognitive measures in 2011 (baseline) and changes in cognition between 2011 and 2013 (first follow-up). We obtained difference-in-differences (DID) estimates of the famine effects by exploiting temporal variation in the timing and duration of famine exposure across six birth cohorts born between 1958 and 1963, together with geographical variation in famine severity at the prefecture level. Results After adjusting for gender, marital status and provincial fixed effects, we found that the 1961 cohort who experienced full-term prenatal and partial-term postnatal exposures to famine had lower scores on the Telephone Interview of Cognitive Status (TICS), a test of drawing pentagons, and general cognition at age 50 years compared with the unexposed 1963 cohort. Adjusting for education, the famine effects on drawing pentagons and general cognition were fully attenuated, but the effect on TICS persisted. We also found a robust negative famine effect on the longitudinal change in general cognition during the 2-year follow-up in the 1959 cohort. Conclusions Severe nutritional deprivation during prenatal and postnatal periods has a lasting impact on cognitive performance in Chinese adults in their early 50s.

Abstract
OBJECTIVE Several studies have revealed that exposure to famine in early life was associated with higher body mass index(BMI) and waist circumference, and most of them used data from cross-sectional studies and defined those born before or after the famine period as non-exposed participants, which ignored the effects caused by age. Our objective was to study the effects of undernutrition in early life on overweight, obesity and abdominal obesity in those aged 54-56. METHODS This was a retrospective cohort study with the status at age of 54-56 as outcomes. 1092 participants born between 1959 and 1961 from 2015 wave of China Health and Retirement Longitudinal Study (CHARLS) were defined as exposed and 1616 born between 1955 and 1957 from 2011 wave of CHARLS were defined as control. We used the prevalence odds ratios(ORs) to estimate the risks of overweight, obesity, abdominal obesity, and stratified by famine severity and sex separately for comparisons. RESULTS Exposed group had higher risks of overweight (OR 1.357, 95%CI 1.067,1.727) and obesity (OR 1.356, 95%CI 1.001,1.836) in women, not in men. Participants in exposed group were more likely to have abdominal obesity (OR 1.362, 95%CI 1.139,1.629), regardless of famine severity and gender. CONCLUSION Undernutrition in early life increased the risks of overweight and obesity in women not in men. And the risk of abdominal obesity was increased with the experience of undernutrition at early age both in men and women.
